| Abstract Scope |
Offered promising methods of high-performance coatings with exposure to high temperatures obtained under SHS(self-propagating high-temperature synthesis) conditions. To increase the corrosion resistance it is necessary to saturate the surface layer with elements that will form passive skin. The mechanism of coating degradation as a result of friction, wear and corrosion or other dynamic loads, the relationship between the composition, processing methods, and microstructural features are considered. To improve resistance at high temperatures, it is necessary to saturate the surface layer with elements that form an oxide film layer, having the following composition - Cr2O3, Al2O3, TiO2, SiO2, which protect the metal from destruction. The high hardness of the resulting alloy coating and the ability to withstand an oxidizing atmosphere at high temperatures of 900-1100 °C allows them to be used in metallurgy, mechanical engineering and aircraft building. Tests in an oxidizing atmosphere showed a weight loss of 34-65 mg/m2. |
