AB  - The industrial requirements in the 21st century are environmentally friendly and light construction materials with good physical-mechanical properties manufactured from cheap natural raw materials available in large quantities. One of these materials is basalt. Basalt is a natural igneous rock of volcanic origin, with a significant amount in Serbia. Basalt belongs to the group of non-hazardous and eco-friendly materials. Andesite basalt aggregate from the "Donje Jarinje" site, Serbia, was used as the starting natural raw material for obtaining the glass-ceramic material. The aggregate is from 2 to 5 mm in size. The aggregate was milled in the tungsten-carbide vibrating cup mill for 30 min to obtain a fine powder for synthesis. The homogenization of andesite basalt powder and binder was carried out in the mortar and pestle for 10 min. The paraplast was used as a binder with a content of 0.6 wt.%. After that, uniaxial pressing of the powder at a pressure of 50 MPa was performed. A forming green compact, cold isostatic pressing was performed with a pressure of 230 MPa to increase its density. The sintering was carried out at the temperature of 1060 °C for 60 min in the air. The sintered glass-ceramic sample was a relative density of 99.5%, a macrohardness of 6.7 GPa and a fracture toughness of 2.2 MPa·m1/2 [1]. The andesite basalt powder was characterized using the laser light diffraction method, X-ray diffraction method and scanning electron microscopy. Sintered glassceramic material was characterized using the X-ray diffraction method, Archimedes principle, scanning electron and optical light microscopy and the Vickers hardness test. The glass-ceramic material obtained by sintering andesite basalt powder could be used for various industrial applications in the civil engineering, mechanical, chemical, and petrochemical industries, as well as for the making of containers to store nuclear waste.

AB  - In this work, the basalt deposits site from southern Serbia was used as a matrix for the composite materials. The corrosion behavior of basalt matrix composites with various ratios of commercial stainless steel 316L (5, 10, 15, and 20 wt.%) and bulk basalt produced by sintering in the air (t=1060ºC and τ=60 min) were studied by immersion corrosion technique. The samples were immersed in a solution of artificial acid rain H2SO4:HNO3 = 9:1 at ≈ pH 3 to measure the concentration of released metal ions using inductively coupled plasma-optical emission spectrometry (ICP-OES). The elements Fe, Cr, Mn, and Ni were monitored, while the others were below the limit of quantification. The concentrations of the metal ions in the solution were studied over 15 weeks. The ions release rate from all the sintered samples was found to follow the Weibull cumulative distribution function (CDF). This means that the release rate changes over time and allows us to calculate the characteristic times of ion release. The changes in the samples were monitored by light microscopy (LM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and weight loss. Sintered basalt shows high resistance to corrosion with a characteristic time of about 18 years for Fe and more than 25 years for Cr and Mn. The weight difference between the initial and after 15 weeks of exposure to the solution (sintered basalt) was not observed. On the other hand, the presence of 5 wt.% steel powder in the sintered basalt accelerates the release of metal ions by about six times. When the steel powder content in the composite materials increases, the metal release rate does not change further, but a weight loss is observed. The characteristic times for Fe, Cr, Ni, and Mn in composite materials are about 5 years. These composite materials can be investigated as materials for using in an acid environment.

AB  - The paper describes the surfacing technology for coating of high-alloyed austenitic stainless steel 316L on the steel S235JR base material. 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. © 2023 Society for Structural Integrity and Life (DIVK).

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.
