    Abstract: A coated body that includes a substrate (22) and a coating scheme (32) on the substrate. The coating scheme (32) on the substrate (22) wherein the coating scheme includes an alpha-alumina coating layer (40) that exhibits a platelet grain morphology at the surface of the alpha-alumina coating layer (40) or a kappa-alumina coating layer (40) that exhibits either a lenticular grain morphology or a polyhedra-lenticular grain morphology at the surface thereof or an alpha-kappa-alumina coating layer (40) that exhibits either a large multifaceted grain morphology or a polyhedra-multifaceted grain morphology at the surface thereof.

    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.
