AB  - A multidisciplinary research method was employed with the intention to create a series of bio-inspired flattened airfoils, observe their aerodynamic characteristics, and analyse their applicability to small devices or to designs of high-speed trains, within the shortest period in the conceptual stage. A research specimen of a kingfisher, selected for biomimicry, was examined with the following methods: visual inspection, analysis of photographs, manufacturing quality control measurement with a 3D laser scanner, and microscopy. A basic multi-arc-line profile, re-engineered from the overlapped specimen shape data and based on the observations, was used for designing a series of seven derived airfoils. The aerodynamic characteristics of the bio-inspired airfoils were obtained with the panel methods at low and moderate subsonic speeds, while the small transonic difference method was used in the high-subsonic speed range. Basic and ellipse-like airfoils produce higher total drag at low and moderate velocities and higher forebody drag in the high-subsonic range when compared to derived and parabola-like airfoils. The obtained critical Mach numbers are in the range from 0.76 to 0.78, where three bionic airfoils show values equal to or smaller than the values of ellipse- and parabola-like airfoils. The profile with the shortest bio-inspired relative chord has a higher critical Mach number value than the parabola-like profile. The sonic lines above these profiles appear at close positions. The applied set of examination methods of the bio-inspired design is not time consuming and produces sufficiently good results in the conceptual stage. Therefore, a further development of unique and adjusted numerical methods and codes at pre-computational fluid dynamics run is encouraged, together with shape parameterization.

AB  - In the times of significant development of high-speed train transportation and taking the primacy over the others, one of the major designing tasks is to predict accurately and fast the vehicle’s main performances, especially aerodynamics. Motivated by the bionic design of representative Japan’s train Shinkansen, the presented bionic design was based on the observations of the kingfisher from Serbian national heritage collection. The specimen beak shape has been measured, by laser scanning, and converted to a mesh. Afterward, the longitudinal cross-section of the beak was implemented to a bionic high-speed train design. As the critical, the conditions of the train’s forehead entering into the tunnel were selected, while the case scheme employed relative motion. The forehead contour distributions of the surface temperature, skin friction coefficient, and the pressure distributions, obtained with computational fluid dynamics, were used for the prediction of the transition zone extension. The anomalies in surface temperature behavior were additionally analyzed by pressure and density distribution inside the tunnel and over the forehead. Besides the gross time history of the pressure derivative of time is in correspondence with the referent, it was interpreted that the true biological form is not fully suitable for adoption for bionic design. The development of this design, employing contour simplification by the close parabolic function will continue in the future. This work suggests an economic and efficient approach to analyze the results of the Reynolds-Averaged Navier-Stokes equations adequate for the concept design stage.

AB  - Carbon based nanophases, such as carbon nanotubes and graphene nanoplatelets, are materials with exceptional properties such as mechanical strength, stiffness, electrical and thermal conductivity. Recently, they have been used as additives to ceramic matrix materials (based on Si3N4, SiC, B4C) with the aim to improve their fracture toughness and strength, tribological behavior (reduce friction acting as solid lubricant and increase wear resistance due to improved toughness), as well as to increase their electrical conductivity. The article brings the summary of these worldwide efforts. It describes the development of the new materials, their preparation by novel techniques, microstructure characterization, mechanical properties, tribological behavior, and electrical conductivity results.

AB  - Metal matrix composites are very inhomogeneous materials, and their properties depend on various parameters (production process, constituents, their interfaces, etc.). The influence of SiC microparticles (40 mu m) reinforcement and graphite macroparticles (200-800 mu m) addition on the mechanical properties of Al-Si A356 alloy, produced by compocasting, has been assessed using macro- and nanoscale measurements of hardness and modulus of elasticity. The Al makes over 90 wt% of the A356 alloy, so the nanoscale measurements were performed on different alpha phase regions on each material (core of alpha phase, eutectic alpha phase, and alpha phase near the phase boundaries alpha phase/secondary phases). The results showed that there is no direct correlation between mechanical properties on macro- and nanoscale. The nanoscale results also showed that the secondary phases (SiC and graphite particles) can have significant effect on the mechanical properties on the atomic level, i.e. in the alpha phase regions very close to the secondary phases.

AB  - The nickel coatings were produced by electroless plating process, without and with addition of 5-7 vol.% SiC nanoparticles of five different sizes (10, 45, 100, 150 and 700 nm in diameter). Coatings were tested in as-deposited and in heat treated (heating at 300 degrees C for 6 h) condition, with two different surface textures preparation. This type of coatings was previously tested and showed improved abrasive wear resistance. Coefficients of friction testing of electroless nickel coatings in contact with bronze counter-body were determined in ambient air and unlubricated conditions. Static and kinetic coefficient of friction, as well as the difference between them, were analysed and discussed. The influence of size of embedded SiC particles in composite coatings, on tested friction properties of these coatings was also determined.

AB  - Real-time external alteration of the internal properties of lubricants is highly desirable in all mechanical systems. However, fabricating a suitable and effective smart lubricant is a long-lasting experimental process. In this study, the film thickness and frictional response of ionic liquid-lubricated non-conformal contacts to an electric field excitation under elastohydrodynamic conditions were examined. Film thickness was evaluated using a "ball-on-disc" optical tribometer with an electric circuit. Friction tests were carried on a mini traction machine (MTM) tribometer with a "ball-on-disc" rotation module and an electric circuit for contact area excitation. The results demonstrate that there is a difference in the behaviour of the ionic liquid during electric field excitation at the evaluated film thicknesses. The results of evaluated film thicknesses demonstrate that there is a difference in the behaviour of the ionic liquid during electric field excitation. Therefore, the ionic liquids could be a new basis for the smart lubrication of mechanical components. Moreover, the proposed experimental approach can be used to identify electrosensitive fluids.

AB  - The paper analyses the corrosion behaviour of naturally and artificially aged AA2024 alloy in NaCl solution and in the presence of an environment-friendly corrosion inhibitor, CeCl3. On the basis of the values of polarisation resistance and corrosion current density, the corrosion resistance of the protective inhibitor film is established as well as the general corrosion resistance of this aluminium alloy. Resistance to pit formation is determined based on the difference in pitting and corrosion potentials while resistance to pit growth is determined based on the amount of charge consumed during pit growth. A scanning electron microscope is used to examine the morphology of the pits formed during the pitting corrosion testing, as well as to determine the cerium content on intermetallic particles and the matrix AA2024 alloy. The corrosion behaviour of AA2024 alloy is investigated after different test periods in NaCl solution and in the same solution with the CeCl3 inhibitor. The corrosion resistance of both tempers of AA2024 alloy is more than one order of magnitude higher in the presence of CeCl3. An explanation of the observed differences in the corrosion behaviour of the naturally and artificially aged AA2024 alloy is proposed. Different corrosion behaviour of the alloy after different test periods is also explained.

AB  - The influence of SiC microparticles reinforcement and graphite macroparticles addition on the friction and wear characteristics of A356 Al-Si alloys, produced by compocasting, has been assessed using a pin-on-disc tribometer. The incorporation of SiC reinforcement increased the coefficient of friction and reduced the wear. The addition of graphite did not reduce the coefficient of friction. In the case of hybrid composite with 1wt% graphite, wear was more or less the same as with SiC reinforced composite, while in the case of hybrid composite with 3wt% graphite, wear was further reduced. On the worn surfaces of hybrid composites, the presence of the discontinuous mixed surface layer, containing graphite and transferred counter-body material, was noticed.

AB  - Surface texturing is one of the surface modification techniques which deliberately change the texture of the surface, in order to improve, among other things, its tribological performance. This is obtained through different patterns, which can be on micro or nano scale, created on the contact surfaces. The performance of a textured surface depends on the shape, geometry and pattern of the surface texture and the operating condition of the components in contact. There is a number of various techniques for surface texturing, among which laser surface texturing is most often used. The different surface texture shapes, different textured area ratios and patterns, different lubrication regimes with different contact geometries and materials have been subject of theoretical and experimental research for many years. This paper reviews the state-of-the-art of researches that consider various surface texturing for tribological application, as well as its effect on performance enhancement. Conclusions of this paper may provide guidance for optimal design of surface textures in practical engineering applications.

AB  - The optimization of wear rate of the nanocomposites with A356 aluminium alloy matrix, reinforced with silicon carbide nanoparticles, was performed through the analysis of the following influences: wt% of the reinforcement, normal load and sliding speed. The nanocomposites were produced by the compocasting process with mechanical alloying preprocessing (ball milling). Three different amounts of SiC nanoparticles, with the same average size of 50nm, were used as reinforcement, i.e. 0.2, 0.3 and 0.5 wt%. Tribological tests were performed on block-on-disc tribometer (line contact) under lubricated sliding conditions, at two sliding speeds (0.25 and 1m/s), two normal loads (40 and 100N) and at sliding distance of 1000m. Analysis of variance (ANOVA) was applied to determine the influence of different parameters on wear value of tested nanocomposites. It was noticed from ANOVA analysis that normal load, with 33.39%, is the most significant factor affecting the wear rate of nanocomposites. The amount of reinforcement, with 28.90%, also has a significant influence on the wear rate, while the influence of sliding speed, with 23.82%, is smaller. It was found that the prediction of wear rate, by using regression model and Taguchi analysis, were close to the experimental values.

AB  - The aim of this study was to investigate the thermal cycling behaviour of NiCr-Al-Co-Y2O3 bond coating in thermal barrier coating (TBC) system with ZrO2-MgO as a top coating. The coatings were deposited by atmospheric plasma spraying (APS) on stainless steel X15Cr13 (EN 1.4024) substrate. The used composite powder NiCr-Al-Co-Y2O3 was mechanically cladded, and the steel substrates were preheated to 160-180 degrees C. The thermal cycling performance of the obtained bond coat and the effect of formed complex ceramic oxides of the Al2O3-Y2O3 system were tested by heating to 1200 degrees C and cooling in air to 160-180 degrees C. The number of performed thermal cycles was 7, 32 and 79. The quality of the obtained coating, as well as its thermal cycling behaviour, was assessed through the microstructural analysis, microhardness and tensile bond strength measurements, and change in chemical composition and microhardness. The obtained results showed that the steel substrate, bond coat oxidation and interdiffusion at bond coat/substrate interface have a significant influence on changes in chemical composition and microhardness of the bond coat. The correlation between oxidation behaviour of NiCr-Al-Co-Y2O3 bond coat and number of thermal cycles was also discussed.

AB  - Metal matrix nanocomposites (MMnCs) comprise a metal matrix filled with nanosized reinforcements with physical and mechanical properties that are very different from those of the matrix. In ZA-27 alloy-based nanocomposites, the metal matrix provides ductility and toughness, while usually used ceramic reinforcements give high strength and hardness. Tested ZA-27 alloy-based nanocomposites, reinforced with different types (SiC and Al2O3), amounts (0.2 wt.%, 0.3 wt.%, and 0.5 wt.%) and sizes (25 nm, 50 nm, and 100 nm) of nanoparticles were produced through the compocasting process with mechanical alloying pre-processing (ball milling). It was previously shown that the presence of nanoparticles in ZA-27 alloy-based nanocomposites led to the formation of a finer structure in the nanocomposites matrix and an improvement in the basic mechanical properties (hardness and compressive yield strength) through the enhanced dislocation density strengthening mechanism. Solid particle erosive wear testing demonstrated that these improvements were followed with an increase in the erosive wear resistance of tested nanocomposites, as well. Additionally, by analyzing the influences of type, amount, and size of nanoparticles on the erosive wear resistance of nanocomposites, it was demonstrated that there is an optimal amount of nanoparticles, which in our case is 0.3 wt.%, and that the presence of SiC nanoparticles and smaller nanoparticles in nanocomposites had more beneficial influence on erosive wear resistance.

AB  - U radu su prikazani rezultati laserskog čišćenja korozivnih i drugih naslaga na metalnom arheološkom predmetu koji je nađen u Dunavu. Korišćen je Nd:YAG laser, energije do 750mJ i talasne dužine λ=1064nm i 532nm. Efikasnost čišćenja je ispitivana u funkciji energije lasera, talasne dužine, broja impulsa, odnosno vremena eksponiranja i vlažnosti površine uzorka. Rezultati skidanja nepoželjnih slojeva sa površine uzorka, kao i morfoloških promena na osnovnom materijalu, ispitivani su optičkom i skenirajućom elektronskom mikroskopijom ( OM i SEM), a ispitivanje mikrohemijskih promena izvršeno je pomoću energijske disperzione spektrometrijske analize (EDX) i rendgensko fluorescentnom spektroskopijom (XRF). Pokazano je da za čišćenje ovog uzorka veću efikasnost ima λ= 532nm i da je uticaj vlažnosti površine na efikasnost laserskog čišćenja veoma mali. Istraživanja obavljena na arheološkom uzorku iz Dunava, pokazuju da je primena lasera u čišćenju nepoželjnih slojeva veoma efikasna, bezbedna i ekološki prihvatljiva.
AB  - The paper presents the results of laser cleaning of corrosive and other deposits on a metal archaeological artefact from the Danube. Nd: YAG laser, energy up to 750 mJ and wavelengths λ = 1064 nm and 532 nm is used. The cleaning efficiency was examined in the function of laser energy, wavelength, and number of pulses, i.e. the time of exposure and moist of the surface of the sample. The results of removal of unwanted layers from the surface of the artefact and morphological changes on the base material were examined by optical and scanning electronic microscopy (OM and SEM). Micro-chemical changes have been determined by energy dispersive X-ray analysis (EDX) and x-ray fluorescence spectrometry (XRF). It has been shown that λ = 532 nm has higher efficiency for cleaning this sample and that the surface moisture has very small influence on laser cleaning efficiency. Research carried out on the archaeological object from the Danube shows that the application of lasers in the cleaning of undesirable layers is very efficient, safe and environmentally friendly.

AB  - Methods of diagnosing aerodynamic characteristics are constantly developing in order to conduct the precise and energy efficient wind tunnel testing of transport vehicles in the prototype design early stages. This is of a special importance when facing the time/cost consumption problems of detection of the transition zone over the simplified design of the high-speed train. Herein the applied thermodynamics found a very significant role in the field of experimental aerodynamics. With the intention of detecting the boundary-layer transition zone the following measurements were applied: the infrared thermography, flow visualization, and drag force measurements. In addition, the CFD was applied to predict the flow behaviour and transition zone, solving PDE consisting of the Reynolds-averaged Navier-Stokes equations, energy equation, and the equation of state for an ideal gas employing density-based solver. The thermal imaging defined the transition zone by simple application, and fast recognition, while the transition bounds were defined in the analysis. The flow visualization confirmed thermography results and the method itself as favourable, especially in the most expensive early phases of redesigning for aerodynamically optimized and energy efficient solutions. The numerical method was confirmed by the experiments, resulting in acceptable differences in the definition of the transition zone. For a better understanding of the phenomenon, the overlapped implementation of the presented methods focused on forced convection showed as the best solution. Based on the experiences of this research, development of the additional equipment and adjustments will be introduced in the future experiments.

AB  - This paper presents the investigation of tribological behaviour of aluminium hybrid composites with Al-Si alloy A356 matrix, reinforced with 10 wt% silicon carbide and 0, 1 and 3 wt% graphite (Gr) with the application of Taguchi's method. Tribological investigations were realized on block-on-disc tribometer under lubricated sliding conditions, at three sliding speeds (0.25, 0.5 and 1 m/s), three normal loads (40, 80 and 120 N) and at sliding distance of 2400 m. Wear rate and coefficient of friction were measured within the research. Analysis of the results was conducted using ANOVA technique, and it showed that the smallest values of wear and friction are observed for hybrid composite containing 3 wt% Gr. The prediction of wear rate and coefficient of friction was performed with the use of artificial neural network (ANN). After training of the ANN, the regression coefficient was obtained and it was equal to 0.98905 for the network with architecture 3-20-30-2.

AB  - Ventilation mill for grinding coal is one of the main steam power plants in the system that makes a significant effect on the level of energy efficiency with its work. The aim of this paper is to increase the energy efficiency of thermo power plant Kostolac B by reducing the problem of wear in ventilation mill for coal grinding. The idea of this research is to investigate the optimum hardfacing technologies to increase wear resistance of impact plates in ventilation mill. Before applying hardfacing on impact plates in the exploitation conditions, it is necessary to model test hardfaced samples for determination of the optimal technology and fillermaterial for revitalization. The relative weight loss of the impact plates after 1440 h period of exploitation in real conditions is very small, 5-8%. The application of this approach can reduce the number of possible repairs and extends the period between them, resulting in significant economic effects. Before and after revitalization of ventilationmill is conducted analyzing of failure during the working period. In this paper, we present time of repair of ventilation mills number 22, 23, 24 and 25, the number of repairs before and after revitalization and cost of repairs.

AB  - The tungsten carbide based WC-Co/NiCrBSi (50/50) and molybdenum based Mo/NiCrBSi (75/25) coatings were investigated under boundary lubricated sliding conditions, and their tribological properties were analysed and compared. These two coatings are in service for a long time, but there are very few papers dealing with their tribological properties, especially in lubricated sliding conditions. The NiCrBSi self-fluxing alloy is one of the popularly used materials for thermal sprayed coating, with relatively high hardness, reasonable wear resistance and high temperature corrosion. Tungsten carbide (WC) is one of the most widely used commercial hard coating materials, and is added to the NiCrBSi coating to improve its hardness and wear resistance. Molybdenum (Mo) is added to the NiCrBSi coating to reduce its coefficient of friction, i.e. to improve its dry sliding wear resistance. The results showed that WC-Co/NiCrBSi coating was more wear resistant, but caused higher wear of the counter-body material. Coefficients of friction were similar for both coatings.

AB  - Wind tunnels are the aerodynamic laboratories which task is to enable high quality  and stabile airflow in controlled volume, a test section, during run time, in order to study the effects of streaming around various aeronautical or nonaeronautical models (airfoils and bluff bodies with complex motorized or robotic constructions). The main requirement that leads to quality and reliable measurement results is a high flow quality in the test section: uniformity of the velocity and pressure fields along and across the test section, low turbulence level and low flow direction angularities or swirling. The knowledge of low parameters enables the exchange of the scientific and technical information, comparison of the experimental results from different wind tunnels and data scaling of the model to the real scale. The turbulence intensity TI significantly affects the wind tunnel results and reduction of turbulence is of the highest importance for the quality measurements. This paper presents the Experimental Aerodynamics Laboratory of the VTI in Belgrade, the equipment and methods of turbulence measurements in the test section stream and around different test models. Wind tunnel facilities maintain equipment and devices for sampling, acquisition and data reduction for various test types, from forces and moment measurements, over the pressure distribution measurements to the advanced measurements, followed with the appropriate flow visualization techniques. The modern instrumentation enables determine flow quality and its influence on tests and measurement results of static and dynamic model characteristics.

AB  - This article presents results of a numerical and experimental study of the temperature distribution inside and on the walls of the ventilation mill in the Kostolac B power plant, Serbia. This is very important because heat exchange between gas mixtures, ventilation mill walls and the environment, influences coal powder temperature, the combustion process, and the emission of greenhouse gases. The most complex multi-phase model in the Euler-Euler approach has been used through the ANSYS FLUENT code, for the numerical simulation of temperature distribution. Two ventilation mill models have been considered, one with zero wall thickness and the other one with steel walls, with and without insulation. An infrared thermographic camera was used for monitoring the temperature distribution on the outside wall of the ventilation mill housing, before insulator reparation, while after the reparation measurements were carried out at the selected points with infrared thermometer. The experimental results were used for verifying the results of the numerical simulation method as well as for detecting the damaged insulation.

AB  - This work focuses on defining loads and fatigue life estimation of helicopter tail rotor blades. The original metal construction of these blades was replaced with a new construction of blades made from composite materials. The subject of this investigation is the precise determination of loads of helicopter composite tail rotor blades together with experimental verification of their fatigue strength. In this research to determine loads of tail rotor blades computational fluid dynamics (CFD) numerical simulations are used. To study the fatigue behavior of composite blades, the blades are here tested under static and fatigue load spectra. For determination of aerodynamic loads of tail rotor blades in this investigation, two computation models are used. In first model, an isolated tail rotor blade is considered. In the second computation model, the complete helicopter is modeled, including fuselage together with main and tail rotor blades. The tail rotor hub is not included in these computational models. To verify the strength of the composite structure of the tail rotor blade, it is tested under the static load and fatigue load spectra. The experimental fatigue test results under the load spectrum are included.

AB  - Numerical simulation of 3D multiphase flow is performed to determine the velocity field in the fan mill. The mixture model of the Euler-Euler approach is used. Recirculating gas is a primary phase that carries granular phases including the coal powder and sand. The latter causes heavy wear of mill impact plates. The optimal form of hardfacing geometry and technology has an impact both on velocity magnitude and direction of flow in such a way as to reduce plate wear. This paper presents results of surface modification (based on numerical simulation), implemented on impact plates of the fan mill in the Kostolac B power plant in Serbia. Fishbone hardfacing is made in order to increase the lifetime of impact plates and extend the period between overhauls of fan mills. The experimental tests of fishbone surfacing plates, in exploitation conditions, show that the applied modification, hardfacing technologies and coating materials, give expected results. The application of this hardfacing in the form of a fishbone is simpler, faster and more economical compared to complete overlaying and honeycomb impact plate surfacing. The relative weight loss of base plate after an 1440-hour period of exploitation is 8%, while the weight losses for the hard-faced plate is below 7%.
