FIELD: technological processes. ^ SUBSTANCE: vacuum-plasma application of double-layer coating is carried out. As bottom layer nitride of titanium, aluminium and silicon is applied, in which silicon content amounts to 0.24-0.26%. As top layer nitride of titanium, aluminium and silicon is applied, which contains 0.8-0.83% of silicon. Application of coating is implemented with application of three cathodes, which are installed in horizontal plane, from which two opposite ones contain titanium and aluminium, and cathode installed between them contains titanium and silicon. All three cathodes are used in application of bottom layer. Top layer is applied using cathode that contains titanium and silicon and one cathode that contains titanium and aluminium. ^ EFFECT: increase of cutting tool operability and quality of its processing. ^ 1 tbl, 1 ex |
