METHOD OF PRODUCTION OF THE MULTILAYER COATING FOR THE CUTTING TOOL Russian patent published in 2007 - IPC C23C14/32 B23B27/14 

FIELD: chemical industry; metal-working industry; other industries; method of deposition of the wear-resistant coatings on the cutting tool.

SUBSTANCE: the invention is pertaining to the methods of deposition of the wear-resistant coatings on the cutting tool and may be used in the metal-working. The technical result of the invention is the increased functionability of the cutting tool. The base layer is deposited out of nitride or carbonitride of the compound of titanium, silicon and aluminum at their ratio of (in mass %): - titanium 86.0-87.3, silicon - 0.7-1.0, aluminum - 12-13. The upper layer is deposited out of the nitride or carbonitride of the compound of titanium, silicon and chromium at their ratio of (in mass %): - titanium - 87.5-88.9, silicon - 0.7-1.0, chromium - 10.4-11.5. Deposition of the coating layers is exercised by three cathodes located horizontally in one plane. The first cathode is made composite out of titanium and aluminum. The second cathode is made composite out of titanium and chromium and is placed counterly to the first one. The third cathode is manufactured out of titanium and silicon alloy and placed between them.

EFFECT: the invention ensures the increased functionability of the cutting tool.
