Abstract

Presently, the modifying multilayer composite coatings have been increasingly used for upgrading performance characteristics of different products. The quality of these coatings and, consequently, efficiency of product properties modification strongly depends on the coating properties such as hardness and adhesive strength of the “coating-substrate” interface and coating interlayer boundaries. Therefore, in present paper a problem of improving accuracy of measurement and control of desired parameters of multilayer composite wear-resistant coatings is considered. An analysis of applied control methods and their quality indicators and capabilities is carried out. An approach to control the surface characteristics of products having the coatings as well as results of research of adhesion parameters and hardness of a wide range of the latest-generation multilayer composite wear-resistant coatings are presented.
