METHOD OF PRODUCING A WEAR-RESISTANT COATING FOR A CUTTING TOOL Russian patent published in 2020 - IPC C23C14/06 C23C14/24 B23B27/14

Abstract RU 2716388 C1

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. Vacuum-plasma application of wear-resistant coating of nitride or carbonitride of niobium and chrome compound at their ratio, at. %: niobium 48.8, chromium 51.2. Coating is applied by three cathodes arranged horizontally in one plane, the first and the second of which are made from niobium and located opposite to each other, and the third one is made of chromium and placed between them.

EFFECT: increased functionality of cutting tool.
