The invention relates to a hard material layer for the coating of mechanically and corrosively stressed parts of any substrate materials. This includes tools, tool inserts, bearings and corrosively stressed assemblies. It can also be used in electronics and optics as well as for decorative purposes.n n n According to the invention, the hard material layer formed from carbon or boron nitride layers has an amorphous network structure which is similar to that in the hexagonal crystalline phases. It has a hydrogen content of 5 atom% to 50 atom%, and there is a layer component consisting of metal and / or boron and / or silicon and / or noble gases in the range from 1 atom% to 85 atom%. |
