摘　　要：铝合金具有许多优良性能,广泛用于航空、航天、舰艇及能源化工等工业部门,但是其耐磨损性能较差。本研究利用全方位离子注入与沉积(PⅢ&D)技术来强化处理铝合金表面,采用离子注入+过渡层+耐磨损层的复合强化处理工艺,通过摩擦磨损试验和压痕方法来研究不同的过渡层结构和厚度对强化层抗磨损性能和结合力的影响规律。试验结果表明,通过优化过渡层结构和厚度,强化层耐磨损性能和结合能力有了很大的提高。Aluminium alloy is used in aviation,astronaviga- tion,naval vessels and energy chemical widely because of performance characters but stand wear and tear is bad.The paper introduces strengthening treatment of aluminum alloy surface by Plasma Immersion Ion Implantation And Deposi- tion and analyses effects of transition layer structure and thickness on characters of stand wear and tear and cohesion of strengthening layer by friction and wear test and indenta- tion method under compound treatment of plasma immersion ion implantation and transition layer as well as anti-abrasive layer.The results show that characters of stand wear and tear and cohesion of strengthening layer are increased.
