FIELD: technological processes. ^ SUBSTANCE: vacuum-plasma application of double-layer coating is carried out. As bottom layer nitride of titanium, chrome and aluminium is applied, which contains 9-10% of aluminium. As top layer nitride of titanium, chrome and aluminium is applied, which contains 6.3-7.0% of aluminium. Application of coating is implemented with application of three cathodes, which are installed in horizontal plane, from which two opposite ones contain titanium and chrome, and cathode installed between them contains titanium and aluminium. At that all three cathodes are used in application of top layer, and bottom layer is applied using cathode that contains titanium and aluminium and one cathode that contains titanium and chrome. ^ EFFECT: increase of cutting tool operability and quality of its processing. ^ 1 tbl, 1 ex |
