Immersion treatment of titanium in aqueous solutions containing various kinds of ion concentrations of calcium and phosphate (pH 5.8, 7.0, and 8.0) were attempted to accelerate calcium phosphate precipitation on titanium in body fluid. The performance was confirmed using scanning electron microscopy, X-ray diffractometry, and Fourier transformed infrared absorption spectrometry with a reflection absorption spectrometer of the specimen immersed in Hanks' solution. Calcium phosphate precipitation on titanium in Hanks' solution is accelerated by the immersion treatment in aqueous solutions containing calcium and phosphate ions. The amount, composition, and shape of calcium phosphate precipitate vary according to the pH and ion concentrations of the solutions in which titanium is immersed. This method is effective for the surface treatment of inside pore narrow space of titanium materials.
