FIELD: technological processes.
SUBSTANCE: invention relates to application of wear-resistant coatings on a cutting tool and can be used in metalworking. Vacuum plasma sandwiched coating is applied. First, bottom ply of niobium nitride is applied. Then upper layer of nitride of niobium and chrome is applied. Coating layers are applied by three cathodes arranged horizontally in one plane, the first and second of which are made of niobium and are located opposite to each other, and third is made of chromium and placed between them, wherein lower layer is applied using first and second cathodes, and upper layer is using said three cathodes.
EFFECT: increased functionality of cutting tool.
