METHOD FOR PRODUCING WEAR-RESISTANT COATING FOR CUTTING TOOL Russian patent published in 2018 - IPC C23C14/24 C23C14/02 B23B27/14 

FIELD: technological processes.

SUBSTANCE: present invention relates to methods of application of wear resistant coatings on a cutting tool and can be used in metalworking. Method involves performing vacuum-plasma deposition of a wear-resistant coating of nitride of titanium, aluminum, silicon, zirconium and niobium at the following ratio, mass%: titanium 57.25, aluminum 9.43, silicon 0.86, zirconium 23.34, niobium 9.12. Coating application is carried out horizontally in one plane by three cathodes. First cathode is made of an alloy of titanium and silicon, second one is made of an alloy of titanium and aluminum and is placed opposite the first, and third is made of a compound of zirconium and niobium and is placed between them.

EFFECT: result of application of the wear-resistant coating is higher cutting efficiency of the tool.
