AB  - The fracture of engineering materials is always an undesirable phenomenon, which primarily can endanger human lives, create economic losses, and lead to downtime and unavailability of mechanical parts. The main drawback that still prevents the broader use of ceramic and glass-ceramic materials is the tendency to brittle fracture due to extremely low toughness. Due to the appearance of cracks, the mechanical properties and structure of the material degrade irreversibly, which can lead to catastrophic failure of the mechanical element or construction. This drawback can be overcome by synthesizing novel composite materials with glass-ceramic matrix and metal reinforcement with improved fracture toughness.
This research examined two materials: a glass-ceramic material and a composite material based on glass-ceramic-metal. The glass-ceramic material is obtained from andesite basalt powder, while the glass ceramic-metal composite is made from the glass-ceramic matrix of andesite basalt powder and a metal reinforcement of stainless steel powder in the content of 20 wt%. The aggregate of andesite basalt from Serbia was used as the starting natural raw material for obtaining the glass-ceramic matrix. The austenitic stainless steel powder of the commercial grade Surfit TM 316L was used as a reinforcement. Both materials were obtained using powder metallurgy, which consisted of the following phases: crushing of andesite basalt aggregate, sieving of the stainless steel powder, homogenization of powder and binder, cold uniaxial pressing of the powder, cold isostatic pressing of green compact and sintering as the final phase to obtain a high-density solid sample.
The andesite basalt, and 316L stainless steel powder were characterized using a scanning electron microscope and X-ray diffraction method. The sintered samples of glass-ceramic and glass-ceramic-metal were characterized with an optical light microscope, scanning electron microscope, and Vickers hardness test.
Based on the obtained results, it can bu concluded that the presence of metallic particles in the glass-ceramic matrix leads to a slight decrease in hardness while contributing to an increase in the materials fracture toughness by about 33% [1]. During crack propagation in the glass-ceramic matrix, different crack particle interactions were observed: crack stops, deflects, or bridgings when encountering the spherical metal particle. These interaction phenomena and mechanisms of crack propagation in the glass-ceramic-metal composite lead to an increase of crack propagation resistance.

AB  - Compound Ti2AlC is a MAX phase discovered in the early 1960s.  It is well known that Ti2AlC has excellent physical and mechanical properties and chemical stability [1]. On the surface of Ti2AlC, at high temperatures, a stable, protective oxide layer, Al2O3, is usually formed [2], whose coefficient of thermal expansion is approximately equal to the coefficient of thermal expansion of Ti2AlC [3]. If this Al2O3 layer is compact, it stops further oxygen penetration and protects Ti2AlC from further oxidation. Due to its excellent oxidation resistance, MAX phase Ti2AlC has great potential in producing protective coatings for components in the industry that are exposed to high temperatures [4,5]. Coating Ti2AlC can be applied to the substrate by different thermal spraying processes. Cold spraying (CS), high velocity air fuel (HVAF), and high velocity oxygen fuel (HVOF) processes can be singled out as particularly interesting due to the possibility of applying thicker coatings to the substrate [6].
This paper describes the technology of applying the Ti2AlC phase on heat-resistant steel using the HVOF system of the third generation, which uses a mixture of oxygen and kerosene as fuel. Also, the filler material, which was in the form of powder, and the microstructure of the obtained coating were characterized by scanning electron microscopy (SEM). The Ti2AlC coating was successfully applied and a relatively good mechanical bond was achieved with the substrate. The goal of surfacing the Ti2AlC coating was a potential application for protecting steel from oxidation at elevated temperatures.

AB  - One of the most responsible elements of modern steam boilers are steam superheaters and reheaters.
These heating surfaces are inside the boiler chamber and consist of tubes connected to the inlet and
outlet header. Due to the complexity of service conditions, boiler tubes are exposed to processes of
gradual degradation, and consequently a decrease in operating performance and reliability.
In the operation of thermal power plants, irreversible metal losses resulting from corrosion can
cause tube failure and plant outage. Considering the loss of materials, gas corrosion in the dry gas
atmosphere due to the high temperature is of great importance. Gas corrosion can be expressed in
the boiler tubing system due to the presence of sulfur compounds in the flue gases. For this reason,
it must be borne in mind that the outer surface of a tube of final reheater has different damage
mechanisms during operation, and one of them is gas corrosion. Gas corrosion causes material loss
and provides a site for crack initiation and propagation, which can compromise the integrity of the
pressure vessel.
In this paper, a tube of a final reheater from a 210 MW power plant was tested. The tube was in
service 200,000 h at a working temperature of 540 °C and a maximum working pressure of 4.6
MPa. The tube is made of low alloy Cr-Mo-V steel, class 12H1MF (GOST). After long-term
service, a rough surface and loss of the material in the form of a crater were observed on the outer
surface of the tube as a result of the effect of gas corrosion, together with the change of
microstructure due to elevated service temperature. The measured depth of damage to the tube is
120 m. The presence of gas corrosion on the tube was confirmed and measured by an optical
microscope, Figure 1.

AB  - In the present study, andesite basalt originated from the deposit site ???Donje Jarinje???, Serbia, was examined as a potential raw material for high-density ceramics production. The production of high-density ceramics included dry milling, homogenization, cold isostatic pressing and sintering in the air. To determine the optimal processing parameters the sintering was conducted at 1040, 1050, 1060, 1070 and 1080 ??C, and afterwards the sintering duration was varied from 30 to 240 min at the optimal sintering temperature of 1060 ??C. Characterization of the starting and sintered materials included the estimation of particle size distribution, density, hardness and fracture toughness complemented with X-ray diffraction, optical light microscopy, scanning electron microscopy and energy dispersive spectroscopy analysis. Phase transformations did not occur during processing in the investigated temperature range from 1040 to 1080 ??C. The obtained research results showed that 99.5% of relative density and the highest hardness and fracture toughness values of 6.7 GPa and 2.2 MPa??m1/2, respectively, were achieved for the andesite basalt sintered at 1060 ??C for 60 min in the air. The results of the present study confirmed that the sintered andesite basalt can be used as a high-density ceramic material for various industrial applications.

AB  - One of the important tasks of evaluating the integrity of mechanical process elements and structures is to determine the local mechanical properties. In this paper, experimental and numerical analyses of the mechanical behavior of an output inter-heater tube, made of 12H1MF heat-resistant steel, was performed after 200,000 h of exploitation. During exploitation, the tube was exposed to various mechanisms of damage including gas corrosion. The tube was cut from a pipe system during reparations of a thermal power plant, and then cold-deformed by bending to obtain a U-bend tube, which was then used in the experiment. For this purpose, a specimen holder made of structural steel S235 was specifically designed to test such a sample. The U-bend tube was then exposed to the external compressive load during the experiment. Experimental research was based on the application of the 3D digital image correlation (DIC), while a finite element method (FEM) was applied in numerical simulation performed by using the Abaqus software package. The 3D DIC is an optical and contactless experimental method that allows measurements of displacement fields and deformations of geometrically complex structures. The Aramis system was used for the experimental analysis as well as for verification of the numerical model. During the experiment, the von Mises strain field was measured at the top of the U-bend tube, in the tightening zone, as it represents a critical place for crack initiation and propagation during the work of an inter-heater. Based on the obtained results and a comparative analysis of experimental and numerical values of the von Mises strain field at the U-bend tube, deviation of the model predictions of about 18 % was determined. The FEM predicted smaller values of the von Mises strain field compared to the DIC method. This is the result of an incomplete geometry applied in the model due to deformation that occurred in the bend zone of the U-bend tube, loss of material and the tube surface damage due to the influence of gas corrosion during 200,000 h of exploitation.

abstract = "One of the important tasks of evaluating the integrity of mechanical process elements and structures is to determine the local mechanical properties. In this paper, experimental and numerical analyses of the mechanical behavior of an output inter-heater tube, made of 12H1MF heat-resistant steel, was performed after 200,000 h of exploitation. During exploitation, the tube was exposed to various mechanisms of damage including gas corrosion. The tube was cut from a pipe system during reparations of a thermal power plant, and then cold-deformed by bending to obtain a U-bend tube, which was then used in the experiment. For this purpose, a specimen holder made of structural steel S235 was specifically designed to test such a sample. The U-bend tube was then exposed to the external compressive load during the experiment. Experimental research was based on the application of the 3D digital image correlation (DIC), while a finite element method (FEM) was applied in numerical simulation performed by using the Abaqus software package. The 3D DIC is an optical and contactless experimental method that allows measurements of displacement fields and deformations of geometrically complex structures. The Aramis system was used for the experimental analysis as well as for verification of the numerical model. During the experiment, the von Mises strain field was measured at the top of the U-bend tube, in the tightening zone, as it represents a critical place for crack initiation and propagation during the work of an inter-heater. Based on the obtained results and a comparative analysis of experimental and numerical values of the von Mises strain field at the U-bend tube, deviation of the model predictions of about 18 % was determined. The FEM predicted smaller values of the von Mises strain field compared to the DIC method. This is the result of an incomplete geometry applied in the model due to deformation that occurred in the bend zone of the U-bend tube, loss of material and the tube surface damage due to the influence of gas corrosion during 200,000 h of exploitation. Experimental analysis has confirmed that the U-bend tube, after 200,000 h of exploitation, can remain in service even if it is damaged due to the effect of gas corrosion.",

AB  - In this study, two erosion protection MMC coatings with WC particles were deposited by the plasma transferred arc (PTA) welding. One of the coatings with tungsten carbide WC in the NiBSi matrix (WC/NiBSi), and the second coating WC in NiCrBSi matrix (WC/NiCrBSi) was deposited by the flame spray process on the same substrate material S235JR steel. Experiments were performed using a gas blast sand erosion test facility with high-velocity erodent particles impact (approximately 100 m/s) at different particle impact angles (20 degrees-45 degrees), with an objective to study erosion wear characteristics and mass loss of two MMC coatings. Microstructural characterization of MMC coatings was done by scanning electron microscope equipped with energy-dispersive X-ray spectroscopy, whereas X-ray diffraction analysis was used for identification of present phases. The hardness of coatings was determined by Vickers hardness measurements. WC/NiBSi obtained by the PTA process shows superior hardness and erosion properties.

AB  - Parts of industrial machines and structures are often exposed to aggressive environments, which in a short period of time can cause the loss of their integrity. Depending on working conditions, a surface of the material can be exposed to various mechanisms of damage, of which corrosion damage stands out. Commercial stainless steel have a significant application in making machine parts in the industry because of their outstanding properties. However, the high prices of this material can sometimes be a limiting factor. For this reason, the idea is to replace expensive stainless steel with a composite material with lower price and improved mechanical properties.
Austenitic stainless steel is a material which is widely used in an industry primarily due to good corrosion resistance. Powder of commercial austenitic stainless steel (SURFIT TM 316L) of the diameter from 45 to 63 µm was used, in our experiment. The steel powder has a spherical shape which is obtained by gas atomization. The source of glass was andesite basalt rock from the locality "Donje Jarinje" Leposavic, the Republic of Serbia. Basalt is a hard aluminosilicate rock which has a relatively low melting point and low viscosity. The composite material was manufactured by mechanical mixing of stainless steel powders with freshly crushed basalt rock in diameter about 10 µm. The composite material consists of stainless steel and different content of basalt.
The green compact was obtained by a hydraulic pressing of the mixture, with a pressure of 150 MPa using a steel mold. Sintering is done at 1250 ⁰C an a time of 30 minutes in a high-temperature vacuum furnace.
Semi-quantitative analysis of andesite basalt powder is obtained by energy dispersive X-ray spectrometry (EDS). Starting powder as well as sintered composites were characterized by X-ray diffraction method (XRD), Morphology of powders and microstructure of sintered sample were followed by scanning electron microscope (SEM) and a light optical microscope (LOM). The hardness of the composite material is determined by the VIckers method.

AB  - Danas, kao i prethodnih godina, produžetak radnog veka mašinskih delova i
konstrukcija u cilju smanjenja troškova održavanja postrojenja od izuzetne je
važnosti za industriju. S obzirom da su delovi u industriji, tokom eksploatacije,
izloženi različitim radnim uslovima, kao što su trenje, korozija, abrazija,
erozija i drugi oblici habanja, koji dovode do njihovog oštećenja kao i gubitka
materijala na površini. Postupci zaštite površinskih slojeva materijala danas
su različiti, a jednu značajnu grupu čine postupci metalizacije, pomoću kojih
se rastopljeni ili omekšani dodatni materijal nanosi na pripremljenu površinu
supstrata formirajući prevlaku različite namene. Imajući u vidu sve postupke
metalizacije, plazma metalizacija predstavlja postupak sa najvišom temperaturom
u procesu nanošenja prevlake. Visok kvalitet dobijenih prevlaka,
omogućava primenu plazma metalizacije u gotovo svim granama industrije.
U ovom radu, predstavljen je princip rada, područje primene, prednosti i
nedostaci kao i značaj plazma metalizacije u vazduhu, kao najčešće korišćenog
postupka plazma metalizacije.

konstrukcija u cilju smanjenja troškova održavanja postrojenja od izuzetne je
važnosti za industriju. S obzirom da su delovi u industriji, tokom eksploatacije,
izloženi različitim radnim uslovima, kao što su trenje, korozija, abrazija,
erozija i drugi oblici habanja, koji dovode do njihovog oštećenja kao i gubitka
materijala na površini. Postupci zaštite površinskih slojeva materijala danas
su različiti, a jednu značajnu grupu čine postupci metalizacije, pomoću kojih
se rastopljeni ili omekšani dodatni materijal nanosi na pripremljenu površinu
supstrata formirajući prevlaku različite namene. Imajući u vidu sve postupke
metalizacije, plazma metalizacija predstavlja postupak sa najvišom temperaturom
u procesu nanošenja prevlake. Visok kvalitet dobijenih prevlaka,
omogućava primenu plazma metalizacije u gotovo svim granama industrije.
U ovom radu, predstavljen je princip rada, područje primene, prednosti i
nedostaci kao i značaj plazma metalizacije u vazduhu, kao najčešće korišćenog
postupka plazma metalizacije.",

AB  - In order to extend service life of equipment and machine parts, or to increase
resistance of mechanical parts exposed to severe conditions, different coatings are applied. There are numerous options in the process of providing a coating to mechanical components in order to protect them. Being versatile, and providing for an array of different materials makes plasma spraying a very popular process, although it is not the best choice for others. Materials in the form of powder commonly used in the process are oxides (TiO2, ZrO2, ZrSiO4, Cr2O3, Y2O3, their mixtures, etc.), carbides, borides, nitrides and cermets (WC–Co and Cr3C2–NiCr is the most widely applied one). In the process of plasma spraying, plasma is generated within the plasma torch via an electric arc. Depending on the material being coated or substrates and their different properties, a large number of different process parameters can be adapted to suit the specific need. The plasma spraying process can be implemented as: 1) atmospheric plasma spraying, where the plasma jet exits the torch into the atmospheric environment; 2) controlled atmosphere plasma spraying, where the jet is exiting into a chamber providing the controlled atmosphere (Ar); 3) low pressure plasma spraying or vacuum plasma spraying, where the jet is exiting
the torch into a low pressure chamber at vacuum conditions; 4) plasma spraying
physical vapor deposition as hybrid process.
