METHOD OF OBTAINING WEAR-RESISTANT COATING FOR CUTTING TOOL Russian patent published in 2017 - IPC C23C14/06 C23C14/24 B23B27/14

Abstract RU 2630736 C1

FIELD: metallurgy.

SUBSTANCE: vacuum-plasma deposition of wear-resistant coating of niobium nitride or carbonitride, titanium and aluminium at their ratio, at %: niobium 64.6, titanium 27.6, aluminium 7.8. Coating plies are applied by three cathodes arranged horizontally in one plane. The first and second cathodes are made of niobium and are arranged oppositely to each other, and the third is made of an alloy of titanium and aluminium and is positioned between them.

EFFECT: higher cutting tool efficiency.
