“…The ASTM G32-92 cavitation erosion test was also used to evaluate the anti-erosion performance of chemical vacuum deposition (CVD) W/WC coatings, applied on Ti6Al4V alloy aircraft parts to prevent from water droplet erosion (WDE). It was found that a hierarchical coating microstructure demonstrated better performance compared to a monotonic columnar grain structure [281].…”

Earlier studies have shown that 30 L steel, used for the manufacture of hydraulic machinery equipment elements, has greater resistance to cavitation wear than 20 GL steel. This paper presents the results of experimental studies of the solid particle erosion resistance of 30 L structural steel samples with different surface modifications based on nitriding and boriding processes. The characteristics of the modified near-surface layers were determined. The results of the solid particle erosion resistance tests carried out according to the ASTM G76-13 standard are presented. The research results demonstrated that boriding processes worsen the solid particle erosion resistance of 30 L steel at flow impact angles of 30° and 90°. All the considered variants of surface nitriding at an impact angle of 90° do not worsen the solid particle erosion resistance of 30 L steel samples, while at an impact angle of 30°, they increase the solid particle erosion resistance by at least 10–20%.

“…The most widespread methods of TBC application are: 1) kinds of plasma spraying: Atmospheric Plasma Spraying (APS), Low-pressure Plasma Spray (LPPS), Solution Precursor Plasma Sprayed (SPPS); 2) Chemical Vapor Deposition (CVD); 3) Chemical Gas-dynamic Spraying (CGDS) [11][12][13][14][15]. Of much interest is the sol-gel procedure allowing one to apply coatings on complex-shaped articles (as distinct from APS and Electron Beam Vacuum Plasma Deposition (EB-PVD)), as well as multilayer coatings.…”

Thermal expansion of refractory ceramics CaZrO3, MgAl2O4, La2Zr2O7 and YSZ-12 was studied. The samples of the complex oxides were synthesized by solution combustion synthesis with glycine; the fuel:oxidant ratio was varied depending on the character of redox reaction. The linear thermal expansion coefficient (LTEC) of ceramics was measured on the samples with an initial density 23–52%. The maximal sinterability of 89–92% after 6 h annealing at 1550 °С was demonstrated by La2Zr2O7 and YSZ-12, and the minimal values (78–82%) – by CaZrO3 and MgAl2O4. All materials have close LTEC values, from 9.0 to 9.6·10–6 K–1.
