METHOD OF PRODUCING WEAR RESISTANT COATING FOR CUTTING TOOL Russian patent published in 2015 - IPC C23C14/06 C23C14/24 B23B27/14 

Abstract RU 2548858 C2

FIELD: process engineering.

SUBSTANCE: invention relates to application of wearproof coating on cutting tool and can be used in machining. Vacuum-plasma application of wearproof coating is performed, coating being composed of titanium, aluminium, silicon, molybdenum and zirconium nitride or carbonitride at the following ratio, wt %: titanium - 39.9, molybdenum - 14.2, aluminium - 12.1.1, silicon - 1.3, zirconium - 32.4. Application is executed by three cathodes arranged horizontally in one plane. First cathode is made of molybdenum and aluminium alloy, second cathode is made of zirconium is arranged opposite the first one while third cathode is made of titanium and is arranged there between.

EFFECT: higher cutting efficiency.
