Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

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 µm 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 nonuniform 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 physicomechanical properties make the deposited material promising for use as a protective material for machines and tools operating in extremely difficult working conditions.
