摘要: A coated cutting insert (20) is described having a substrate (40) that has flank surface (22) and rake (24) edge (26) at their intersection, wear-resistant coating scheme (44) adheres to the substrate, includes one or more layers (52) of alumina, hafnia zirconia. wear indicating scheme. The (56) M(OxCyNz) wherein M selected from group comprising following titanium, hafnium, zirconium, chromium, titanium-aluminum alloy, hafnium-aluminum zirconium-aluminum chromium-aluminum alloys, x>0, y=0, z=0 y + z > 0. method making also provided for by applying an as-deposited non-wear layer treating it convert layer.
