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 the vacuum-plasma deposition of a wear-resistant coating of nitride of titanium, aluminum, silicon, niobium and iron at the following ratio, mass%: titanium 60.53, aluminum 10.19, silicon 0.96, niobium 26.94, iron 1.38. Coat 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 from an alloy of titanium and aluminum and is placed opposite to the first one, and third is made of a composite of niobium and iron and placed between them.

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