摘　　要：羟基磷灰石（ＨＡ），由于具有良好的生物亲和性及与机体的骨性结合性，是金属植入材料的理想涂层材料。目前，主要采用等离子体喷涂、涂覆和烧结的方法将ＨＡ 涂覆在金属植入体表面或直接使用羟基磷灰石植入体用于临床的修复重建手术，但均因强度和涂层结合力不足，在应用中受到限制。采用离子束辅助沉积技术将离子注入与物理气相沉积相结合，进行钛及钛合金的表面处理，对制备ＨＡ／Ｔｉ植入体具有极大的优越性。本文报导离子束辅助沉积制备ＨＡ／Ｔｉ植入体的设计，并利用世界公认的Ｔｒｉｍ ９６ 程序对制备参数进行计算，为进一步的研究和应用奠定基础。Hydroxy apatite (Ca 10 (PO 4) 6(OH) 2,HA) is a potential material for coating on metal implants owing to its bioaffinity and osteo integration to body. 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.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 HA/Ti implants by ion beam assisted deposition technique and the computation of fabricating parameter using Trim96 program. The present investigation lays a foundation of further researches and application.
