Abstract: Hydroxyapatite (HAP)-coated metal composites were made by the dipping method. The specimen substrates were Ti plates with a thickness of 2 mm. The HAP coating was carried out in HAP-sol for 1 min by the dipping method. The concentration of HAP-sol for the coating ranged from 3.28 to 9.99 wt%. Excellent coating was observed on Ti substrate dipped once in 9.99 wt% sol. A surface pretreated with a sandblasting provided a much better coating than a smooth surface. As the concentration of sol increased, the weight change and the coating thickness increased. Above 7 wt% sol, they increased sharply.
