摘要：
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 alpha-Al2O3, on the outer surface oxide. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
