    摘要: The present invention relates to a multilayer coating system deposited on at least a portion of a solid body surface and containing in the multilayer architecture Al—Cr—B—N individual layers deposited by means of a physical vapor deposition method characterized in that in at least a portion of the overall thickness of the multilayer coating system the Al—Cr—B—N individual layers are combined with 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 thicker than the thickness of the Ti—Al—N individual layers, and thereby the residual stress of the multilayer coating system is considerably lower in comparison to the residual stress of the corresponding analogical Al—Cr—B—N monolayer coating.

    摘要: The present invention provides an optimized hard coating and a workpiece, especially a cutting tool coated with a hard coating to increase tooling performance with difficult to machine materials such as high speed steels, titanium alloys, nickel alloys, austenitic steels and especially hard materials like hardened tool steel having a hardness of higher 50, preferably of higher 55 HRC. This is achieved by a workpiece coated with a wear resistant multilayered comprising at least a first supporting layer and a second nanocrystalline layer, whereas the first layer comprises a coating material of the following composition (TiaAl1-a)N1-x-yCxOy with 0.4
