Abstract

The article describes the study of a coating based on aluminum oxide, obtained by the method of vacuum-arc evaporation on samples of hard alloy VK8 with different values of the bias voltage. A number of tests were carried out, including a scratch test, tribological tests in order to establish the nature of the wear of the coating with the coating technology used. The results showed that under the spraying and testing modes used, this coating is plastically deformed without showing the wear pattern standard for ceramic coatings
