| 摘 要： | 利用电化学实验方法和纳米力学探针技术，通过测量载荷-位移关系曲线，研究了氢对不锈钢钝化膜纳米力学性能的影响，结果表明：随氢含量的增加，不锈钢钝化膜的临界破裂载荷降低，位移偏移量减小，氢导致钝化膜的径向抗拉强度(应力)和弹性模量降低，钝化膜随氢含量的增加而逐渐软化。

| Abstract: | The effect of hydrogen on the nanomechanical properties of passive films formed on 316 stainless steel was investigated using nanoindentation and electrochemical testing techniques. The results showed that the critical fracture load of passive films reduced and the displacement excursion decreased with increasing the concentration of hydrogen. The reduction of radial breaking stress and elastic modulus of passive films is attributed to that hydrogen changes the structure of passive films. |
