チタンの陽極酸化に及ぼす表面状態の影響

抄録

The influence of surface condition on the anodization coloring behavior of titanium has been studied. It was found that uniform coloring was observed on polished surfaces while multiple coloring was observed on pickled surfaces. From the relationship obtained between crystal orientation of base metal and anodized film thickness, it was concluded that the film growth was faster on prism surfaces and was slower on basal surfaces. It was also confirmed by in-depth analysis of anodized surface on Ti alloy that the film was of inward growth type.
