Abstract
The invention relates to a method for the manufacture of coatings having a low coefficient of friction on articles such as mechanical components and tools, with a layer sequence of carbon and a carbide of at least one element in the form of a metal and/or silicon and/or boron being deposited on the article by means of a PVD process. Articles which have such a layer sequence are also claimed. The coating has a low coefficient of friction, is wear-resistant and has a relatively high hardness and also relatively high elasticity.
