Abstract
The present invention relates to a cutting tool insert comprising a substrate and a coating. The coating composed of one or more layers of refractory compounds of which at least one layer comprises a so called MAX-phase defined as Mn+1AXn where n is 1, 2 or 3, M is one of the elements Ti, Zr, Hf, V, Nb, Ta, Cr or Mo, A is Al, Si or S, X is C, N and/or B.

A cutting tool insert comprising a substrate and a coating, the coating comprising one or more layers of refractory compounds of which at least one layer comprises a MAX-phase defined as Mn+1AXn where n is 1 or 3, M is one of the elements Ti, Zr, Hf, V, Nb, Ta, Cr or Mo, A is Al, Si or S, and X is C, N and/or B.
A cutting tool insert comprising:
- a substrate;
- and
- a coating, the coating comprising one or more layers of refractory compounds of which at least one layer comprises a MAX-phase defined as Mn+1AXn where n is 1, 2 or 3, M is one of the elements Ti, Zr, Hf, V, Nb, Ta, Cr or Mo, A is Al, Si or S, and X is (N1−x, Cx) where x is between 0 and 0.6.
