FIELD: technological processes. ^ SUBSTANCE: as bottom layer nitride of titanium, zirconium and iron is applied, which contains 1.2-1.4% of iron, and as top layer same nitride is applied, which contains 0.4-0.6% of iron. Application of coating is implemented with application of three evaporators, which are installed in horizontal plane, from which two opposite ones contain titanium and zirconium, and evaporator installed between them contains titanium and non-magnetic stainless steel. All three cathodes are used in application of top layer, and in application of bottom layer one of cathodes that contains zirconium is not used. ^ EFFECT: increase of cutting tool operability and quality of its processing. ^ 1 tbl, 1 ex |
