| Research Abstract |
The surface modification of titanium may also improve its biocompatibility and osteoconductive properties. Electrolysis was carried out in an acid electrolyte including calcium and phosphate ions. During the electrolysis, the electrode polarities were swapped every one minute. This process was called the polarity inversion electrolysis method. After this treatment, the surface titanium was covered with a thin oxide film including the phosphate ion. Moreover, calcium phosphate with nano in size was deposited on the titanium surface. I report the deposition behavior of calcium phosphate and the characterization of thin oxide film
