| Abstract Scope |
Offered promising methods of applying protective wear-resistant coatings - technology for producing powder coatings by in a high-temperature synthesis (SHS). This kind of protection is the most promising and less costly, since it does not require changes in the technology of materials. To increase the corrosion resistance it is necessary to saturate the surface layer with elements that will form passive skin. In our case, when the ionic passivation potential is reached, oxide films are formed, with 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 retain lubricant on the surface leads to an increase in the resistance of these parts to wear. Tests on the friction machine MT-5 (friction under conditions of shock-dynamic loading) showed that the best wear resistance is provided by protective coatings doped with Si. |
