摘要
采用D/MAX-ⅢB型X射线衍射仪、原位纳米力学测试系统、LKDM-2000型摩擦磨损仪、S-3000N型扫描电子显微镜和CHI660A电化学工作站对经C、N离子注入的1Cr18Ni9Ti奥氏体不锈钢的组织及耐磨性、耐蚀性进行了较深入地研究。研究结果表明,1Cr18Ni9Ti奥氏体不锈钢经离子注入后,注入层硬度提高,摩擦系数降低,耐磨性提高,抗腐蚀性增强;注入N+的剂量为2.44×1017ions/cm2时,注入层的硬度最高,耐磨、耐蚀性最好,性能最佳。
The micmstructure, wear resistance and corrosive resistance of ion implantation austenitic stainless steel 1Cr18Ni9Ti were studied by the X - ray diffraction tester, the full featured nanomechanical testing instrument, LKDM- 2000 friction and wear tester, S - 3000N scaning electron microscopy and CHI660A - electro- chemical workstation. The experimental results reveals that, after the ion implantation into the austenitic steel 1Cr18Ni9Ti, the surface micro - hardness is increased, friction coefficient decreased and the wear resistance and anti - corrosion is improved significantly. When the dose of implanting nitrogen ions was 2.44 × 10^17 ions/cm^2, the implanted surface was hardest, the wear resistance and anti - corrosion properties were best.
