THE MECHANICAL PROPERTIES OF THE COATINGS AFTER MICROARC SURFACE ALLOYING OF STEEL
The mechanical properties of steel 20 after microarc surface saturation with carbon, boron and carbide-forming elements were investigated. Micro-indentation of the surface layer using the Nanotest-600 device was performed, followed by analysis of the obtained P - h diagrams using the Oliver-Farr method, and wear resistance tests were carried out. The results obtained allowed us to determine the method of microarc diffusion saturation, which makes it possible to obtain coatings with the highest complex of mechanical properties.
