【Abstract】

AlCrN coatings are known to exhibit a good mechanical, thermal, and oxidation resistance at severe machining condition, and hence widely used in cutting tool applications. The coating property and performance thereof are increased as the Al content is increased. However, it is generally believed that a highly Al containing AlCrN coating, e.g. Al content more than 65 at.%, tends to provides a poor property, which is due to formation of hexagonal phase in the coating deposited.
In newly developed PVD coating system, AIP-iX, together with the optimization of coating process, we have successfully deposited a highly Al containing AlCrN coatings sustaining a high fraction of cubic phase. The coating shows a 1.5 times better wear resistance as compared to a high-end coated tools for reference.
In this talk, we introduce the KOBELCO PVD technology and demonstrate the feature of AlCrN coating deposited by new PVD system, AIP-iX.
