Title
Anodic oxide films containing Ca and P of titanium biomaterial
Abstract

Anodic oxidation and oxide films of titanium in the new electrolyte of calcium glycerophosphate (Ca-GP) and calcium acetate (CA) were investigated by galvanostatic mode, SEM, XRD and EPMA. The anodic oxide film displayed porosity, intermediate roughness, and high crystallinity. Also, the oxide film is enriched with Ca and P and high in thickness without microcracks. According to the surface properties of the oxide film, the optimum condition was that the concentration of the electrolyte was 0.02 m Ca-GP and 0.15 m CA, and current density and final voltage were 70 A/m2 and ca. 350 V. The oxide film formed in the condition is 0.98 μm (Ra) rough, 5–7 μm thick, adhesive to the underlying substrate, and near 1.67 Ca/P ratio in the oxide film.
