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