Abstract:
1. A multilayer coating system deposited on at least a portion of a solid body surface and containing in a multilayer architecture Al—Cr—B—N individual layers deposited by means of a physical vapour deposition method characterized in that in at least a portion of the overall thickness of the multilayer coating system at least two Al—Cr—B—N individual layers are combined with at least two Ti—Al—N individual layers, wherein the Al—Cr—B—N and Ti—Al—N individual layers are deposited alternately one on each other, and wherein the thickness of the Al—Cr—B—N individual layers is greater than the thickness of the Ti—Al—N individual layers, and thereby residual stress of the multilayer coating system is considerably lower in comparison to residual stress of a corresponding analogical Al—Cr—B—N monolayer coating system.
