摘要
采用D/MAX-ⅢB型X射线衍射仪、X射线能谱仪、S-3000N型扫描电镜、HXD-1000TML/LCD数字式显微硬度计、CETR微观多功能磨损实验机和CHI660A电化学工作站对经N离子注入的316L奥氏体不锈钢和Ti6Al4V合金的组织、硬度、耐磨性和耐蚀性进行了研究。结果表明,316L奥氏体不锈钢和Ti6Al4V合金经离子注入后,注入层硬度提高,摩擦系数降低,耐磨性提高,抗腐蚀性增强;且离子注入后Ti6Al4V合金的综合性能明显优于316L不锈钢,钛合金注入N离子的剂量为3.4×1017ions/cm2时,注入层的硬度、耐磨性和耐蚀性综合性能最好。
The microstructure,hardness,wear resistance and corrosive resistance of N-ion implantated stainless stell 316L and Ti6A14V alloy were studied by the X-ray diffraction tester (D/MAX-Ⅲ B), the X-ray energy spectrometer, S-3000N scaning electron microscopy, HXD-1000TML/LCD microhardness instnunem,the universal multifunctional tester (CETR) and CHI660A- Electrochemical Workstation.The results show that, after the ion implantation into the austenitic steel 316L and Ti6A14V alloy, the surface microhardness increases, friction coefficient decreases, the wear resistance and anti-corrosion improve significantly.The combination properties of Ti6A14V alloy implanted by nitrogen ion are better than austenitic stainless stell 316L.When the dose of implanting nitrogen ions of Ti6A14V is 3.4× 10^17Tions/cm^2,the hardness, wear resistance and anti-corrosion properties of the implanted surface are best.
