| Abstract Scope |
The purpose of the study is to form chromium-alloyed coatings using functionally active blends to increase the heat resistance of the working surface. Compared to coatings obtained under isothermal conditions, the heat resistance is 1.28-1.33 times higher, which can also be explained by the higher concentration of chromium, aluminum, silicon, and titanium, which contribute to the formation of protective oxide films SiO2, TiO2, Cr2O3, and Al2O3.First, a protective coating of CrAl is formed, after which it is alloyed with titanium, chromium and silicon to introduce heat-resistant phases such as TiAl and CrSi2. This multi-stage process significantly increases the ability of the coatings to withstand high temperatures and harsh environments. The low-porosity surface prevents oxygen from penetrating the material, promoting the formation of oxide protective coatings. |
