详细

The elemental and phase composition, macro- and microstructure, hardness, and abrasive wear resistance of coatings obtained via a plasma sputtering of a high-speed steel (HSS) P6M5 powder and a (TiC + 50 vol % of P6M5) powder obtained using a self-propagating high-temperature synthesis procedure are studied. The structural state of oxygen and nitrogen impurities and their effect on the properties of coatings are considered. It is established that the metal-matrix structure of the composite powder remains unchanged in the sputtered coating, which causes a 2.0-fold and 7.6-fold increase in the hardness and wear resistance of the composite coating, respectively, in comparison with the coating obtained via sputtering of steel powder.
