AB  - The paper presents a detailed description of the oil rectification process used in upstream oil and gas plants, including the significant equipment involved. One such equipment highlighted in the study is a pressure vessel utilized as a separator to separate the liquid and gas phases. This pressure vessel has been in operation for over two decades. A thorough examination of the mentioned pressure equipment was conducted during the process evaluation. It was discovered that the internal side of the vessel, particularly its back elliptical head, had suffered extensive damage due to erosion and corrosion, emerging as the most significant cause of the deterioration. The application of RBI-estimation revealed that the vessel falls under the category of highly risk equipment, and there is a significant risk of both environmental and financial consequences associated with its potential failure (leakage). Such failure is anticipated to occur promptly in the area below the wear plate of the vessel's nozzle.

AB  - Failures in industrial plants, which operate under extreme conditions, could occur after a short time of exploitation. Erosion wear of materials is caused by the relative movement of solid particles and the surfaces of components. Such erosive wear can lead to the failure of industrial components in a very short time and/or a sharp decline in the structural integrity of industrial equipment. For example, the wear of the ash disposal system in a coal-burning thermal power plant, due to impact of ash particles with a high content of mineral residues, is a very common case of failure and outages in the operation of such industrial systems.
Two high chromium cast irons (HCCI) were tested to determine the erosion wear. These alloys contain 15% Cr and 25% Cr, and it was tested in as-cast and after heat treatment (annealing). A specially designed installation was used for the gas blast sand erosion test. Type of erodent was foundry quartz sand. Erosion tests were done with high erodent particle velocity (90 m/s) and high erodent feed rate (3000 g/min). This conditions represents those similar to extreme wear conditions of some components of thermal power plants using pulverized high mineral content coals.
Microstructural characterization was done at samples before and after erosion tests, Fig. 1. The main results indicate that matrix plastic deformation and distribution of carbide phase have a significant contribution to erosion resistance of HCCI alloys in such conditions.

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  - A class of ternary layered carbides and nitrides, known as MAX
phases, combines some of the best properties of two distinct
classes of materials: metals and ceramics. Specifically, MAX phases
are stable at high temperatures, resist thermal shock, and some
even form stable and protective oxide layers in oxidizing environments.
Thus, they are excellent candidates for protective coatings
in high-temperature applications. In this context, our focus is on
using kerosene-fueled High-Velocity Oxy-Fuel spraying to deposit
MAX phases onto P91 steel substrates for use as thermal barrier
coatings. The chosen MAX phase for this study is Ti2AlC, which
offers an outstanding oxidation resistance. Our results indicate that
during the spraying procedure, a portion of the MAX phase decomposes,
another portion oxidizes, yet more than half maintains the
initial and desired stoichiometry. Nevertheless, the resulting coating
establishes a stable and robust bond with the steel substrate. In this
presentation, we will discuss the detailed analysis concerning the
relationship between the process, structure, and performance of the
Ti2AlC coating on the P91 steel substrate.

AB  - In this study, two high chromium cast irons
(HCCI) with different chromium content (15%Cr and
25%Cr), in as-cast and annealed conditions (heat-treated,
HT), were tested to determine the erosion wear behavior of
these alloys. Erosion tests were done using a gas blast sand
facility with high erodent particle velocity (90 m/s) and high
erodent feed rate, at an impact angle of 45°, which represents
conditions similar to service conditions of some components
of thermal power plants using pulverized high mineral content
coals. To identify erosion mechanisms, microstructural
characterization was done by a scanning electron microscope
on samples before and after erosion tests. Identification of
microstructural phases was done by X-ray diffraction analysis.
The main results of the tests shown in this paper indicate
that matrix plastic deformation and distribution of carbide
phase have a significant contribution to erosion resistance of
HCCI alloys in severe erosion service conditions.

Coatings were applied by plasma transferred arc welding process. The 5 samples were made using different welding currents while other welding param¬eters were constant. Metallographic analysis of the obtained samples is used to establish a correlation between the micro¬structural constituents and the applied welding current in the surfacing process. According to this it was possible to determine the optimal parameters of coating surfacing. The filler material was in the form of powder, while its charac¬terization was performed by scanning electron microscopy, and the characterization of the obtained coatings by optical microscopy.

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  - This paper presents new methodology for determining the actual stress-strain diagram based on analytical equations, in combination with numerical and experimental data. The first step was to use the 3D digital image correlation (DIC) to estimate true stress-strain diagram by replacing common analytical expression for contraction with measured values. Next step was to estimate the stress concentration by using a new methodology, based on recently introduced analytical expressions and numerical verification by the finite element method (FEM), to obtain actual stress-strain diagrams, as named in this paper. The essence of new methodology is to introduce stress concentration factor into the procedure of actual stress evaluation. New methodology is then applied to determine actual stress-strain diagrams for two undermatched welded joints with different rectangular cross-section and groove shapes, made of martensitic steels X10 CrMoVNb 9-1 and Armox 500T. Results indicated that new methodology is a general one, since it is not dependent on welded joint material and geometry.

AB  - A general procedure for heat exchanger design has been presented in the Heat Exchanger Design Handbook (HEDH) [1], but no precise criterion for determining baffle cut nor baffle spacing has been offered, and the emphasis is only on heat exchanger’s permissible range of application. In this paper, an optimization program has been used to calculate pressure drop, fluid velocity, heat power, overall heat transfer coefficient and middle temperature difference for various baffle cut and baffle spacing for the same type of heat exchanger, using the procedure in HEDH. This could be considered as complementary to the HEDH recommendations and can be used by designers and, generally, engineers for determining the right baffle cut and baffle spacing for their specific cases.

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  - One of the main objectives in research and development of resin based cements (RBCs) is to enhance their clinical longevity and ease of use. In spite of the undeniable technological advances introduced in the last few decades, the polymerization shrinkage i.e. strain that accompanies the chain-growth polymerization of dimethacrylate monomers remains one of the major concerns for the clinical performance of composite restorations. Also, RBCs can produce a considerable amount of heat, due to the light energy from the curing lights and exothermic reaction of polymerization. The purpose of this study was to determine the temperature changes during the photo-polymerization using thermocouples and to measure strain field of the self-etching, self-adhesive RBC, Maxcem Elite (Kerr, Orange, CA, USA) (empty set5 x 1 mm - Group I and empty set5 x 2 mm - Group II) using experimental technique, 3D Digital Image Correlation (DIC) method. Digital images were recorded immediately after photo-polymerization of the samples with a LED-curing unit for 20 s, according to manufacturer's recommendation. Vickers microhardness was determined after photo-polymerization and after 24 h. Temperature curves for both groups indicated similar patterns but the peak temperature of Group II was significantly higher compared to peak temperature of Group I. DIC showed that peripheral zone of the samples had the highest strain values in both groups. Group I indicated significantly higher values of hardness. All the results were material-dependent and probably correlated to the composition of each material, which is not fully disclosed by the manufacturers.

AB  - Corrosion is irreversible process of material degradation. Due to the adverse effects on characteristics of the operating
material, especially in boiler tubing systems, this is one of the most important problems in the functioning of thermal power
plants and it is considered to be the main cause of many outages. The basis and the first step in process of equipment life
estimation done by using common methods, and determination of the probability of failure is the calculation of stresses in
tubes caused by presence of corrosion damage. In this paper are presented stress analyses attained by deterministic method
and finite element method analyses for tubes with internal corrosion damage. Those analyses were performed on a large set
of data collected for the first stage of re-heater at 350MW thermal power plant unit, which was in service for app 60000
hours. Comparison of stress analyses results was done and obtained difference was analyzed, as well as implications of
obtained results on integrity analyses of corrosion damaged tubes. Influence of gained results on remaining life assessment
and probability of failure results were studied as well, since these considerations are important for the risk-based inspection
and maintenance programs.

AB  - Parts of industrial machines and structures are often exposed to the action of aggressive environments, which in a short period of time can provoke the loss of their integrity. It is well known that for extending the service life against erosion and corrosion, protection of the exposed structure zone by coating is frequently used. Various application methods of protective coatings are applied, and the most common are welding and thermal spraying processes. The aim of this study was characterization of coatings made of stainless steel 316L, widely used in chemical and petrochemical industries. The coating was applied on a structural steel S235JR by plasma transferred arc using powder as a filler material. Due to a number of advantages, the plasma transferred arc (PTA) surfacing process has found significant usages in the field of surface protection. This paper presents results of hardness measurements in characteristic zones of the coating and the base material, as well as microstructural characterization of coatings using optical and scanning electron microscopy. Results of EDS analysis of the coating and hardness measurements indicated that a relatively high dilution (26.1 %) of the base material (BM) and the filler material (FM) occurred in a very narrow zone above the fusion line, and thus did not significantly affect the chemical composition of the rest of the coating. Also, erosion resistance tests of coatings were performed by changing the basic functional parameters that is the impact angle and the speed of erodent particles. It was observed that the erosion resistance of the coating material decreases approximately linearly with the increase of the particle speed. Also, with the increase of the impact
