用扫描电子显微镜和Ｘ射线光电子能谱仪分析了ＺＡ２２合金和ＺＡ２２－Ａｌ２Ｏ３复合材料在干摩擦条件下的磨损表面．结果表明：在ＺＡ２２合金磨损表面形成了一层厚约１００μｍ的塑性变形层，而添加Ａｌ２Ｏ３短纤维能够有效地使这种变形层减薄；在垂直于磨损表面的纤维周围的基体明显比其它部位的高；磨损后复合材料表面的元素Ｚｎ被氧化，并有偶件材料的转移物存在．
The wear surface of ZA22 alloy and ZA22-Al2O3 composite under dry friction condition was analyzed by scanning electron microscopy and X-ray photoelectron spectroscopy. The results show that a plastic deformation layer with a thickness of about 100 μm is formed on the wear surface of ZA22 alloy, while the addition of Al2O3 short fibers can effectively thin the deformation layer. The matrix around the fiber perpendicular to the wear surface is obviously more than other parts Of the elemental surface Zn of the composite material is oxidized and there is a transfer of the coupled material.
