Abstract | A coated body (20) that includes a substrate (22) and a coating scheme (36) on the substrate. The coating scheme includes a CVD titanium carbonitride coating layer (41) containing titanium carbonitride grains that are of a pre-selected grain size. The coating scheme further includes a first titanium/aluminum-containing coating layer (48, 52, 56) containing first titanium/aluminum-containing grains applied so as to be farther away from the substrate than the titanium carbonitride coating layer. The first titanium/aluminum-containing grains are of a pre-selected grain size. The coating scheme also includes a CVD alumina coating layer (50, 54, 58) containing alumina grains applied so as to be farther away from the substrate than the first titanium/aluminum-containing coating layer. The alumina grains are of a pre-selected grain size. |
