Effect of passive film on tribocorrosion

为了研究钝化膜再生对钛摩擦腐蚀性能的影响，测量了钛表面机械击穿后再钝化电流的快速瞬变过程。研究发现，新生成钝化膜的生长受强场控制。用大气腐蚀试样的拉伸试验研究了高强度钢的氢脆性能，表明该评价方法简便、易行、适用性强。

To clarify the influence of regeneration of passive film on the property of tribocorrosion, quick transient of repassivation current after mechanical breakdown of the surface of titanium was measured. It has been found that the growth of newly generated passive film is controlled by high field. Hydrogen embrittle property of high strength steels has been also investigated using a tensile test of samples corroded atmospherically, and it has been clarified that the evaluation method is simple, easy and appropriate.
