FIELD: technological processes. ^ SUBSTANCE: on working surfaces of cutting tool double-layer coating is applied with vacuum-plasma method. As bottom layer nitride of titanium, aluminium and molybdenum is applied, which contains 9-10% of aluminium, and as top layer nitride of titanium, aluminium and molybdenum is applied, which contains 6.3-7.0% of aluminium. Application of coating is implemented with application of three evaporators, which are installed in horizontal plane, from which two opposite ones contain titanium and molybdenum, and evaporator installed between them contains titanium and aluminium. All three evaporators are used in application of top layer, and in application of bottom layer one of cathodes that contains molybdenum is not used. ^ EFFECT: increase of cutting tool operability and quality of its processing. ^ 1 tbl, 1 ex |
