FIELD: methods of application of wear-resistant coats on cutting tools; metalworking.
SUBSTANCE: multi-layer coat is applied on working surfaces of cutting tools by vacuum-plasma method. Layers of coat are applied with the aid of three cathodes located horizontally in one plane. Two opposite cathodes are made from titanium and sectional cathode located in between them is made from titanium and aluminum. Lower layer of titanium nitride is applied at temperature of 620°C±10°C and upper layer is made from titanium nitride and aluminum is applied at temperature of 550°C±10°C.
EFFECT: enhanced serviceability of cutting tools; improved quality of treatment.
