METHOD FOR PREPARATION OF MULTI-LAYER COATING FOR CUTTING TOOL Russian patent published in 2008 - IPC C23C14/06 C23C14/16 C23C14/34 B23B27/14 

Abstract RU 2327811 C1

FIELD: technological processes, metals processing.

SUBSTANCE: invention is related to methods of vacuum-plasma application of wear resistant coatings on cutting tool and may be used in metals processing. Lower layer of multi-layer coating is made of nitride or carbonitride of titanium, chrome and iron with ratio of, weight % - titanium 87.2-88.7, chrome 10.0-11.2, iron 1.3-1.6, and upper layer - of nitride or carbonitride of titanium, chrome and aluminium with their ratio of, weight % - titanium 75-77, chrome 10.4-11.5, aluminium 12.6-13.5. Application of coating layers is done with three cathodes that are installed horizontally in one plane. The first cathode is made as assembled from titanium and iron, the second one is made as assembled from titanium and aluminum and are installed opposite to the first one, and the third one is made assembled from titanium and chrome and are installed between them.

EFFECT: increase of cutting tool serviceability.
