摘　　要：铝合金、钛合金等材料具有许多优良性能,广泛用于航空、航天、舰艇及能源化工等工业部门,但是这两种材料的耐磨损性能较差。本研究利用了全方位离子注入与沉积(PIII&D)技术来强化处理这些合金表面,采用离子注入+过渡层+耐磨损层的复合强化处理工艺,通过摩擦磨损试验来研究不同的过渡层结构和厚度对磨损性能的影响。实验结果表明,通过优化过渡层结构和厚度,耐磨损性能有了很大的提高。Because of their variety excellent properties, aluminum and titanium alloy are widely used in aerospace, airplane, ship manufacture, energy source and chemical engineering. However, both of them show a low wear resistance. In our research, plasma immersion ion implantation and deposition was utilized to improve their wear resistance. The method of ion implantation ＋ transition layer deposition ＋ wear resistance layer deposition was applied on these alloys. And by employing the wear testing method, the influences of the structure and thickness of the transition layer on wear resistance were obtained. The experimental results reveal that the wear resistance of these alloys can be improved significantly by optimizing the processing window.
