Outline of Final Research Achievements

The present work examined the curious dissolution and oxidation behavior on anodization of intermetallic compounds and the control of reactivity of intermetallic compounds. The morphology, structure and thickness of oxide layer on intermetallic compounds were different from those predicted based on their compositions. Results obtained indicated that the behavior strongly depended on the difference in anodic current originated from intermetallic compound. It was also found that the small addition of alloying element to intermetallic compound can change the reactivity of the compound drastically.
