ANTIFRICTION COATINGS WITH IMPROVED ABRASION AND WEAR PROPERTIES AND METHODS OF MAKING SAME Russian patent published in 2018 - IPC C23C28/04 

FIELD: polishing.

SUBSTANCE: disclosed is a multilayered antifriction coating and a method for producing such a coating. Multilayered antifriction coating includes a bottom layer selected from a group consisting of CrN, TiN, TiAlN, TiAlVN, TiAlVCN, TiSiN, TiSiCN, TiAlSiN and combinations thereof, wherein the thickness of the bottom layer ranges 5 to 25 mcm, an adhesion promoting layer selected from a group consisting of Cr, Ti, Si, W, CrC, TiC, SiC, WC and combinations thereof, wherein the thickness of the adhesion promoting layer ranges from 5 to 15 mcm, wherein said layer is contiguous with the surface of the bottom layer, and an antifriction layer of diamond-like carbon, wherein the thickness of the antifriction layer ranges 5 to 15 mcm, and said layer contiguous with the surface of the adhesion promoting layer. Adhesion promoting layer is located between the bottom layer and the antifriction layer. Disclosed is a method for producing a multilayer antifriction coating comprising depositing said layers.

EFFECT: providing an antifriction coating with improved abrasion resistance and wear resistance.
