FIELD: measurement equipment.
SUBSTANCE: material of a tested coating is applied onto a working surface and worn by means of attrition. Prior to wear by means of attrition, ionic polishing of the surface of the metal sample is carried out, then layers of wear-resistant coating of different colour are sputtered by ion-plasma method. The total thickness of the applied coating is selected in the range from 100 nm to 20 mcm, and after wear of the coating by attrition they visually and using measurement equipment determine the nature and extent of wear.
EFFECT: increased accuracy of determination of nature and extent of wear of parts with complex geometry, increased efficiency of analysis, possibility to study thin-film coatings.
