METHOD FOR APPLYING COATING ON A METAL-CUTTING TOOL Russian patent published in 2022 - IPC C23C14/06 C23C14/16 C23C14/46 C23C8/36 B32B15/04 

FIELD: tooling.

SUBSTANCE: invention can be used in tool manufacturing when hardening cutting tools by deposition of self-sharpening coatings. The processed metal-cutting tool is placed in a vacuum chamber and its ion cleaning is performed in an inert gas environment, first using a plasma source with an incandescent cathode, and then using an electric arc evaporator. After cleaning, a layer of titanium is applied in an inert gas medium, and then the main wear-resistant layer is applied with simultaneous spraying of Ti and Al in nitrogen, oxygen and acetylene as reaction gases with the formation of a matrix of intermetallic phases TiAl, Ti₃Al, TiAl₃ and filler in the form of TIN, AlN, TiC, AlC, Ti₂O, Al₂O₃.

EFFECT: invention makes it possible to increase the service life of a metal-cutting tool by improving its physical and mechanical properties, for example, adhesion between layers and reducing wear.
