摘要:利用多弧离子镀技术在316L不锈钢和单晶硅上沉积CrCN薄膜,通过X射线衍射仪(XRD)、扫描电镜(SEM)、X射线光电子能谱仪(XPS)、纳米压痕仪、273A电化学工作站和多功能摩擦磨损试验机等对316L不锈钢及CrCN薄膜的微观结构、力学性能、耐腐蚀性能和摩擦学性能进行表征。结果表明:在316L不锈钢上沉积CrCN薄膜后,硬度从4 GPa提高到22 GPa,H/E和 H3/E2分别从0.022和0.002 GPa提高到0.071和0.11 GPa;阳极腐蚀电位从-0.21 V上升到-0.19 V;在大气,去离子水,海水环境下的摩擦系数及磨损率均显著降低,表现出较优异的综合性能。

Abstract: CrCN coating was deposited on 316L stainless steel and single crystal silicon by Multi-Arc ion plating technique. Microstructures, mechanical performance, corrosion resistance and tribological properties in ambient air, distilled water and seawater were systematically investigated by XRD, XPS, SEM, nano-indentation and ball-on-disc tribol-meter. The results showed that hardness of CrCN coating, deposited on 316L stainless steel, increased from 4 GPa to 22 GPa, H/E and H3/E2 increased from 0.022 and 0.002 GPa to 0.071 and 0.11 GPa, relatively. The anode corrosion potential increased from -2.1 V to -1.9 V, the friction coefficient and wear ratio in ambient air, distilled water and seawater could all be significantly reduced. In other words, the coated 316L stainless steel showed a better comprehensive performance than uncoated one.
