Многокомпозиционное покрытие Al-Cr-N для штампового инструмента

Abstract

Increasing the service life of machine parts and mechanisms is an urgent issue at the present time. To solve this problem, various hardening technologies are used in the machine-building industry, in which thermal hardening methods are used: volumetric hardening, electron beam, cathode-arc, laser and plasma methods. The most optimal direction of modifying a tool working with shock loads is the development of new methods of hardening and giving special surface properties, and in particular, the development of hard coatings with special characteristics. In view of this, the creation of multicomposition coatings, which, along with high hardness, could have sufficient resistance to cracking due to a combination of hard and relatively soft layers, is a promising area of research.
