Abstract
A method of making a coated body wherein the method includes the following sequential steps. First, providing a substrate Second, applying by chemical vapor deposition a titanium carbonitride coating layer that has a thickness equal to between about 0.5 micrometers and about 25 micrometers Third, applying by chemical vapor deposition a first titanium/aluminum-containing coating layer that has a thickness between a greater than zero micrometers and about 5 micrometers. Fourth, applying by chemical vapor deposition an alumina coating layer that has a thickness between greater than zero micrometers and about 5 micrometers. The first titanium-containing coating layer and the alumina coating layer makes up a coating sequence, and the method includes applying a plurality of the coating sequences by CVD.
