The study of multilayer coatings based on MoN(MoZr)ZrN and (TiMo)N/(TiMo), (CrZr)N/(CrZr) obtained by the method of vacuum-arc deposition

In the article the results of experimental studies of multilayer coatings MoN(MoZr)ZrN and (TiMo)N/(TiMo), (CrZr)N/(CrZr), obtained on A570 Grade stainless steel samples with a Ra roughness of up to 0.09 mu m are presented. Coatings were formed by vacuum-arc evaporation of cathodes in the installation Bulat-6. After deposition of multilayer coatings by scanning electron microscopy and microanalysis, a non-uniform distribution of zirconium, chromium, nitrogen and molybdenum was found on the surface of the samples. The research results show that good tribological properties in combination with improved physico-mechanical properties make the deposited material promising for use as a protective material for machines and tools operating in extremely difficult working conditions.
