Coating () deposited on a surface of a substrate () comprising a multi-layered film () consisting of a plurality of A-layers and a plurality of B-layers deposited alternating one on each other forming a A/B/A/B/A . . . architecture, the A-layers comprising aluminium chromium boron nitride and the B-layers comprising aluminium chromium nitride and not comprising boron, whereas the multi-layered film () comprises at least a first portion () and a last portion (), wherein the average boron content in the first coating portion () is higher than the average boron content in the last coating portion (), and both the first coating portion () and the last coating portion () exhibit inherent compressive stresses and wherein the inherent compressive stress in the first coating portion () is lower than it in the last coating portion ().

AlCrN-based coating providing enhanced crater wear resistance

A coated product having coating that includes a layer of hard material having a defined multi-ply layer structure, thereby significantly minimizing or preventing heat input into the coated substrate resulting from the effect of thermal hot spots.

Hard material layer for reducing heat input into a coated substrate

A hard material layer system with a multilayer structure, comprising alternating layers A and B, with A layers having the composition MeONin atomic percent and B layers having the composition MeONin atomic percent, where the thermal conductivity of the A layers is greater than the thermal conductivity of the B layers. Meand Meeach comprise at least one metal of the group Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, and Al, pindicates the atomic percentage of Meand pindicates the atomic percentage of Meand the following is true: P=P, nindicates the oxygen concentration in the A layers in atomic percent and nindicates the oxygen concentration in the B layers in atomic percent and the following is true: n&#x3c;n, and mindicates the nitrogen concentration in the A layers in atomic percent and mindicates the nitrogen concentration in the B layers in atomic percent and the following is true: p/(n+m)=p/(n+m).

Hard material layers with selected thermal conductivity

The present invention relates to a coating system comprising at least one multi-layered film formed of alternated A- and B-nanolayers deposited one on each other characterized in that the A-nanolayers contain essentially aluminum chromium boron nitride and the B-nanolayers contain essentially aluminum chromium nitride.
