Oxidation behaviors of TiAl(La)N coatings deposited by ion plating

The effect of Al and La on the oxidation rates of TiAl(La)N coatings were estimated. Addition of not only Al but also La effectively reduced the oxidation rate. In particular, La had acted to induce the preferential formation of dense α-Al 2O 3 on the outer surface oxide.
