Outline of Final Research Achievements

In order to improve both the scratch strength and the hardness of (Al,Cr)N coating film, the cathode material of an aluminum/chromium/tungsten target was used in adding the tungsten (W) to the cathode material of the aluminum/chromium target. To clarify the effectiveness of the aluminum/chromium/tungsten-based coating film, we measured the thickness, hardness and scratch strength of aluminum/chromium/tungsten-based coating film formed. The hardened steel, the sintered steel or the hardened sintered steel was turned, and the tool wear was experimentally investigated.
The following results were obtained: (1) The hardness of both the (Al60,Cr25,W15)(C,N) and the (Al64,Cr28,W8)(C,N) was over 3000 HV0.25N. (2) The scratch load of both the (Al60,Cr25,W15)(C,N) and the (Al64,Cr28,W8)(C,N) was over 130 N. (3) The aluminum/chromium/tungsten-based coating film can be used as a coating film of cemented carbide cutting tools in cutting hardened steel, sintered steel or hardened sintered steel.
