The calcium phosphate including Hydroxapatite (Ca_<10>(PO_4)_6(OH)_2 : referred to as Hap) utilizes as a biomaterial, because that resembles the principal ingredient of the tooth and bone and have superior biocompatibilty. Through coating calcium phosphate on metallic biomaterial such as the commercially titanium, the biocompatible character can be given to the material together with its mechanical strength. Some trials have been conducted for applying these coated materials to the artificial bone and so on. In this study, the optimum condition of the Hap films formation by electrochemical method was investigated by employing QCM (Quartz Crystal Microbalance), FE-SEM and EDX. Adhesive strength of coated HAp films evaluated by the scratch test. Also, biocompatible character was examine by immersion text into quasi-human body fluid.
