| 摘 要： | 钼和硫2种离子同步注入9Cr18不锈钢样品.用针盘摩擦磨损实验机测定了注入样品的耐磨性能,用俄歇电子能谱仪(AES)测量注入样品成分深度分布,并检测了样品硬度.与钼或硫单独注入9Cr18样品相比,钼和硫的同步注入使样品的摩擦因数和磨损寿命显著改善,此改性效果与注入层中注入的元素分布的叠加有关.采用计算机模拟了注入过程,模拟的结果有助于揭示改性层的特点和注入增强效果的机制.

| Abstract: | Mo and S ions were simultaneously implanted into 9Cr18 stainless steel samples. The frictional properties of the implanted samples were assessed using a pin-on-disk tester and the elemental depth profiles were measured. The dual-element implantation process reduces the coefficicent of friction by a factor of 2 and increases the low-friction lifetime by a factor of 4 compared to the 9Cr18 surface with Mo or S implantation alone. This enhancement is related to the synergistic coexistence of the implanted elements at the same place. The process is investigated by using computer simulation. The simulation results help disclose the characteristics of the modified layer and explain the effects of dual-element ion implantation. |
