-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.
Ceramic cutting tools have a large potential by high speed processing of difficult-to-cut steels and alloys, however due to its fragility they don’t assure the required reliability level of cutting process. For improving the operational characteristics of the ceramic cutting tool combined treatment can be used namely the preliminary planetary grinding of the insert surface and the following deposition of the vacuum-plasma coatings (TiCr)N, (ZrCrHf)N and other.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
