摘要：

Hydroxy-apatite (Ca-10(PO4)(6)(OH)(2), HA), owing to its bioaffinity and osteo-integration to body, is potential materials for coating on metal implants. At present, in addition to bulk HA directly used in restoration and reconstruction surgery, hydroxy-apatite is also coated on metal implants by plasma-spraying method, adhesion and sintering. However, these kinds of biomaterials are restricted in application due to their insufficient strength and weak bonding between substrate and coating. It is of great advantage to modify the surface of titanium and its alloy by ion-beam-assisted deposition (IBAD) combining ion implantation with physical vapor deposition (PVD). This paper is focused on the design of Ti/HA implants by ion-beam-assisted deposition technique and the computation of fabricating parameter using Trim 96 program The present investigation lays a foundation of the further research and application.
