CUTTING INSERT WITH STRUCTURE OF WEAR PROOF COATING AND INDICATION OF ABRASION, AND METHOD OF ITS PRODUCTION Russian patent published in 2012 - IPC B23B27/14 B23P15/28 B32B15/00 

Abstract RU 2469819 C2

FIELD: metallurgy.

SUBSTANCE: cutting insert with coating 20 has thrust plate 40 with rear surface 22 and front surface 24 and cutting edge 26 at their intersection, and wear proof coating structure 44 adhered to thrust plate to include one or several layers 52 of coating from one or more of the following materials: alumina, hafnium oxide and zirconium dioxide. Coating indicating surface abrasion is applied on wear proof coating structure. Coating 56 indicating surface abrasion contains M(OxCyNz), where M is selected from the group consisting of one or more following materials: titanium, hafnium, chromium, alloy of titanium and aluminium, alloy of hafnium and aluminium, alloy of zirconium and aluminium, alloy of chromium and aluminium, and alloy thereof, while x>0, y=0, z=0 and y+z>0. Invention covers also the method of production of above described cutting insert.

EFFECT: higher hardness and longer life.
