| Research Abstract |
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.
