FIELD: technological processes. ^ SUBSTANCE: vacuum-plasma application of double-layer coating is carried out. As bottom layer nitride of titanium, silicon and iron is applied, which contains 1.3-1.5% of iron. As top layer nitride of titanium, silicon and iron is applied, which contains 0.4-0.6% of iron. 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 stainless non-magnetic steel. All three cathodes are used in application of bottom layer, and bottom layer is applied using cathode that contains titanium and stainless non-magnetic steel and one cathode that contains titanium and silicon. ^ EFFECT: increase of cutting tool operability and quality of its processing. ^ 1 tbl, 1 ex |
