Tool or machine component and method for increasing the resistance to wear of said component

摘要

The invention relates to a layered system especially designed for tools or machine components that are operated in conditions of insufficient lubrication or dry-running. The inventive system initially consists of a base body (1) and a hard material layer system (2), supplemented by a metal layer (3) and finally a sliding layer system (4) whereby that latter is preferably made of carbide, especially tungsten carbide or chrome carbide and dispersed carbon.
