| 摘 要： | 报道了M2型高速工具钢在Cu,Al离子注入后表面硬度及抗磨损性的变化。对注入样品进行了显微硬度及抗磨损性的测量和XRD与RBS分析，观察了表面强化与离子注入条件之间的关系。结果显示，注入样品与未注入样品相比，表面硬度及抗磨损性均有显著提高。分析结果表明，Cu,Al离子注入后样品中产生了不同的相，它们对表面强化所起的作用不同。

| Abstract: | Changes of surface hardness and wear resistances in M2 type steel implanted by Cu Al ions were reported. The dependence of surface strengthening on ion species and dose was studied by X-ray diffraction (XRD) and Rutherford Backscaterring Spectroscopy (RBS) for microhardness and wear resistances measurement. It is shown that both hardness and wear resistance increases apparently after ion implantation. XRD analysis indicates that different phases formed after Al Cu ions implanted. It is also suggested that Cu, Al ions have different role in surface strengthening. |
