The present study was investigated on the morphologic changes of Ti surface by the
immersion in Hanks` solution and aqueous solutions containing calcium and phosphate
ions in turns and the surface of the treated specimens were characterized by using SEM
and XRD.
Amounts of calcium phosphate apatite were increased by when immersed in aqueous
solution containing calcium and phosphate after Hanks' solution than when immersed in
Hanks' solution only.
Needle and plate-like apatites were observed when immersed in the solutions of weak
acid and neutral condition, while granular multiple layers were seen in the solutions of
weak alkali condition.
The precipitations of calcium phosphate on Ti surface were increased by dilution in
weak acid and weak alkali solution. On the other hand, amounts of precipitates in
neutral solution were increased in non-diluted and 2 times diluted solution than 5 times
diluted solution.
The results of XRD showed that only Ti peaks were detected in N, A1 conditions
while peaks of brushite in A2, A3, B1, B2, B3, C1 conditions and peaks of synthetic
hydroxyapatite were seen in C2, C3 conditions.
For the precipitation of bioactive apatite, immersion in alkali solution is favorable by
immersion method rather than neutral or acid solution.
