摘要
利用熔融铝合金的直接氧化反应制备了具有含油自润滑特性的Ａｌ２Ｏ３／Ａｌ复合材料。通过对磨面的ＳＥＭ观察及能谱分析，测定了金属相和显微孔隙对复合材料磨损性能的影响，初步探讨了Ａｌ２Ｏ３／Ａｌ复合材料的磨损机制。
The sliding wear behaviour of Al2O3/Al composite prepared by Lanxide process was investigated in this paper. It is shown that microporosities which are disadvantageous to the mechanical property of the composite can provide a better lubrication due to their oilcontained and oilsupplied effects. According to the SEM observation and energy dispersive Xray analyses, the influence of metal phases and porosities upon the composite sliding wear property was discovered, which leads to an initial discussion of the sliding wear mechanism of Lanxide Al2O3/Al composites.
