| Research Abstract |
It was clarified that corrosion fatigue strength of Mg alloy was significantly improved by electro-Ni plating on the specimen surface. In addition, anodizing of the Mg alloy is not expected to improve the corrosion fatigue strength. However hybrid treatment, i.e., anodizing and painting treatments is effective to improve the corrosion fatigue strength.
