“…Glass-ceramics based on basalt have a very fine and homogeneous structure, excellent physical and mechanical properties, chemical resistance, high wear and corrosion resistance and can replace metallic materials in the construction of structural parts of equipment in metallurgy and mining [5][6][7][8][9][10][11]. Technical ceramic based on basalt find application in all industrial branches where the problem with the chemical resistivity and wearability is actual: electrical engineering, chemical engineering, metallurgy and mining [12][13][14][15][16][17][18]. According to the literature, in the world, basalt is used as a raw material for the production of basalt wool, thin and super thin basalt fiber, cast products, basalt plastics, anti-corrosive materials, building materials, thermal insulation materials [19][20][21][22].…”

The paper analyzes the morphology of cavitation damage of raw and sintered basalt samples. The experiment was conducted using the ultrasonic vibratory cavitation test method according to the ASTM G-32 standard. During the determination of the resistance to the effect of cavitation, a change in the mass of samples was observed in the function of the cavitation time of operation. The morphology of damage caused by the effect of cavitation was followed by scanning with an electron microscope, and the level of degradation of the surface of the samples was quantified using the image analysis. The results showed a significantly higher degree of resistance of sintered basalt, with a cavitation rate of 0.019 mg/min relative to raw basalt, with a cavitation rate of 0.738 mg/min. After 120 minutes of exposure to the cavitation effect, a smaller number of small pits on the surface of sintered basalt were observed, while a higher level of damage to the surface with the appearance of numerous pits was found in raw basalt, which can be connected in some places to larger and deeper pits in some places. The obtained results indicate the possibility of using sintered basalt for the production of parts that will be exposed to the effects of high cavitation loads.

“…8,9) Combined with lower temperature protection of glass and high temperature protection of ceramic, the ceramic-glass material having comprehensive properties of glass and ceramic could have a better anti-oxidation performance than a single glass or ceramic material. [10][11][12] Silicon would take shape a continuous glassy SiO 2 layer at the interface between steel and scale during heating treatment. 13) Due to low concentration of defects, the silicon layer had excellent oxidation resistance.…”

In this paper, a MgO-SiO 2 -Al 2 O 3 -ZnO ceramic-glass coating sprayed on carbon steel was studied at high temperature. The property of the MgO-SiO 2 -Al 2 O 3 -ZnO ceramic-glass coating was analyzed in a range of 900°C and 1 150°C a share. The experimental results indicated that the MgO-SiO 2 -Al 2 O 3 -ZnO coating exhibited powerful anti-oxidation property for carbon steel. The MgO-SiO 2 -Al 2 O 3 -ZnO coating could improve the anti-oxidation performance of carbon steel by 84% at 1 050°C for 60 min. The Ea of blank and coated samples were 108.65 and 202.55 kJ/mol, respectively. The k p of the blank sample (0.61 mg 2 ·cm − 4 ·s − 1 ) was 7.6 times as much as that of coated sample (0.08 mg 2 ·cm − 4 · s − 1 ). It demonstrated the coating slowed down oxidation reaction rate and then improved the anti-oxidation performance of carbon steel. The possible protection mechanisms of the MgO-SiO 2 -Al 2 O 3 -ZnO ceramic-glass coating were also investigated using the SEM-EDS, XRD and TG-DTA characterization methods. The mixture formed between the coating and steel substrate (such as MgFe (x = 0.4, 0.85, 0.94)) played a role in blocking the spread of ions and improved the oxidation resistance of carbon steel during heating treatment. The synergy of the formed Al, Mg and Zn compound layers in the coating could also block spread of oxygen and iron ions and exert an influence on enhancing anti-oxidation property.

AlPO4 based coatings were prepared on Ti‐6Al‐2Zr‐1Mo‐1V titanium alloy using aluminum phosphate as a binder and Al2O3/Cr2O3 based mixing particles as the fillers. The microstructure, phase and chemical composition of the coatings were analyzed by SEM, XRD and EDS techniques. The high temperature infrared emissivity values of coated and uncoated titanium samples were tested. The results show that the coating had a higher infrared emissivity value (>0.8) than titanium substrate (0.15–0.3) in the wide wavelength range of 5–20 mm, which is attributed to the uniform dispersion of high emissivity Al2O3 and Cr2O3 particles in the AlPO4 binder matrix. The coated titanium samples exhibited excellent oxidation resistance performance with significantly decreased oxidation rates at 600 and 800°C. The mass gain of the coated sample kept at a low and stable constant of 0.15 mg/cm2, significantly lower than that of titanium substrate (0.54 mg/cm2) when oxidized at 600°C up to 100 h.
