  • Patent number: 8926722
    Abstract: 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.

  • Publication number: 20150001064
    Abstract: Coating method for arc coating or arc ion plating coating of substrates in a vacuum chamber in which using an arc evaporator solid material that functions as cathode is evaporated, during arc evaporation the motion of the cathode spot on the solid material surface is accelerated using a magnetic field for avoiding ejection of a large amount of macro-particles or droplets from the solid material surface, negative charged particles resulted from the arc evaporation flow from the cathode to an anode, characterized by the motion of the negative charged particles from the cathode to the anode fundamentally doesn't cause an additional increase of the absolute value of the potential difference between cathode and anode allowing a lower increment of the substrate temperature during coating.
