FIELD: technological processes. ^ SUBSTANCE: vacuum-plasma application of double-layer coating is carried out. As bottom layer nitride of titanium, zirconium and silicon is applied, which contains 7-8% of zirconium and as top layer nitride of titanium, zirconium and silicon is applied, which contains 24-25% of zirconium. At that application of coating is implemented with application of three cathodes, which are installed in horizontal plane, from which two opposite ones contain titanium and silicon, and cathode installed between them contains titanium and zirconium. All three cathodes are used in application of bottom layer, and top layer is applied using cathode that contains titanium and zirconium and one cathode that contains titanium and silicon. ^ EFFECT: increase of cutting tool operability and quality of its processing. ^ 1 tbl, 1 ex |
