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 layer of niobium nitride is applied. Then upper layer of nitride of niobium and molybdenum 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 from molybdenum and placed between them, wherein lower layer is applied using first and second cathodes, and upper layer – using all three cathodes.
EFFECT: result of application of the multi-layer coating is higher cutting efficiency.
