摘要：

The electrodeposition of bioceramic coatings of calcium phosphates on metal substrate is a newly developed method for preparing implanted bio-medical devices[1-2]. It is proposed to have a remarkable higher bioactivity and excellent bio-capability for the electrodeposited bioceramic coating, because it may produce a pure structure and composition of hydraxiapatite (HAP) during electrodeposition process at room temperature. However, the bonding force of electrodeposition bioceramic coating to the metal substrate is too weak. It has become a major problem in developing electrodeposition technique for preparing bioceramic coatings of calcium phosphates on metal substrate. The present work has been emphasized to develop an approach for preparing HAP bioceramic coatings, which has strong bonding force both in the bulk phase of HAP coating and to the metal substrate.
