| dc.description.abstract | Cr3C2-NiCr metal-ceramic coatings have found wide application in the protection of machine parts and equipment operating under extreme conditions. In this study, Cr3C2-NiCr based detonation coatings which have been subjected to pulse-plasma treatment were studied. The study showed that IPO reduced the surface roughness by 48 %, reduced the coating friction coefficient by about 2 times, increased the hardness of the coatings from the original 12 GPa to 16.2 GPa and improved their wear resistance by 2 times compared to untreated coatings. Pulse-plasma treatment provides qualitative formation of coatings from metal-ceramic material of Cr3C2-NiCr system with complex heterogeneous structure-phase state, where the layered structure of areas of carbide particles and matrix metal in immediate proximity from “carbide-matrix” border with selections in matrix of dispersed secondary carbides is revealed. | ru_RU |
