摘　　要：纯铁表面沉积Ｔｉ和Ａｌ膜的同时，用Ｎ＋离子束注入增强沉积，成功地形成了性能优越的表面改性层．与ＺｒＯ２陶瓷球对磨结果表明，经Ａｌ＋Ｎ＋或Ｔｉ＋Ｎ＋离子束增强沉积后，纯铁的表面显微硬度及磨损性能得到了较大的提高，磨痕形貌和元素分布观察结果表明：离子束增强沉积（ＩＢＡＤ）处理前后。By using N + ion beam implantation combined with Ti or Al film deposition, surface layers with improved tribological properties were obtained successfully. Reciprocal sliding wear tests carried out against ZrO 2 ceramic ball show that after Al+N + or Ti+N + ion beam assisted deposition (IBAD), the tribological properties of iron were improved greatly. So is the increase in surface microhardness. The wear track morphology and distribution of element indicate that:the wear mechanism has changed prior to and after IBAD.
