【 摘 要 】

LiAlxOy films with thicknesses of 65-200 nm were deposited by the ALD technique on an Mg-10Li-0.5Zn alloy. The ALD-deposited LiAlxOy films have an amorphous structure and exhibit properties of low friction coefficient, high hardness/elastic (H/E) ratio, strong adhesion, smooth surface roughness and conformable coverage. These excellent properties of ALD-deposited LiAlxOy films can significantly improve the wear performance and cavitation-erosion resistance of Mg-10Li-0.5Zn alloy. (C) 2010 Elsevier B.V.
