Zirconium is expected to be applied for novel biomaterials because of excellent mechanical properties, corrosion resistance, and biosafety. However, zirconium does not form calcium phosphate precipitates spontaneously on the surface when it is immersed in simulated body fluids unlike titanium that is widely used in orthopedic and dental field. The surface treatment must be required to change the surface property of zirconium to form calcium phosphate precipitation, leading to improve the hard tissue compatibility. In this study, the micro-arc oxidation (MAO) treatment was applied to zirconium and it was confirmed that calcium phosphate layers were formed on the MAO-treated zirconium samples. The mechanism and the behavior of the calcium phosphate formation were also investigated by SEM, EDS, XRD, and ICP-OES analysis.
