Abstract

A method for manufacturing a tool or machine component increases wear resistance by providing a base body made of a metal or of a hard metal and having a surface. At least a portion of the surface is vacuum coated with a hard solid layer system having at least one layer of a material selected from the group consisting of nitrides, carbides, oxides, carbonitrides, oxynitrides, and oxycarbonitrides of at least one metal. A metallic intermediate layer having the at least one metal is vacuum deposited on the hard solid layer system, and a sliding layer system is vacuum deposited on the metallic intermediate layer.
