FIELD: technological processes.
SUBSTANCE: invention is related to methods of multilayer coating preparation for cutting tool and may be used in metal working. Vacuum-plasma application of double-layer coating is carried out. Lower layer is applied from nitride or carbonitiride of titanium, aluminium and iron compound, with their following ratio, weight % - titanium 83.7-85.2, aluminium 13.0-14.2, iron 1.8-2.1, and top layer is made of nitride or carbonitride of titanium, aluminium and chrome compound with their following ratio, weight % - titanium 74.1-76.8 , aluminium 13.0-14.5, chrome 10.2-11.4. Coating is applied with three cathodes installed horizontally in single plane. The first cathode is made as composite from titanium and iron, the second one - composite from titanium and chrome and is installed opposite to the first one, and the third one - composite of titanium and aluminium and is installed between them.
EFFECT: increase of cutting tool serviceability.
