ABSTRACT:
A coated cutting tool that has a rake face and a flank face with a cutting edge at the juncture of the rake and flanks faces, a substrate, and a coating bonded to the substrate. The coating has a coating scheme that includes a layer of a Group IVB metal-aluminum alloy applied by physical vapor deposition, and a layer of alumina applied by physical vapor deposition to the layer of the Group IVB metal-aluminum alloy.
