Abstract
A coated body that includes a substrate and a coating scheme on the substrate. The coating scheme includes a CVD titanium carbonitride coating layer containing titanium carbonitride grains that are of a pre-selected grain size. The coating scheme further includes a first titanium/aluminum-containing coating layer 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 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.
