Abstract
The paper presents the study results of the grind finishing effect on the surface quality of cermet wear-resistant coatings obtained by plasma spraying of mechanical mixtures. The main component for the formation of mixtures was alumina with additions of nickel or cobalt powders. The sprayed compositions surface analysis indicates the structure specificity of cermet coatings. The presented typical images of topographies and profilograms of the investigated compositions surfaces show that coatings of nickel-ceramic mixtures have an acceptable level of roughness after grind finishing.
