摘　　要：从生物相容性的角度考虑 ,羟基磷灰石 (HA)是人体组织置换种植体最适合的陶瓷材料。但陶瓷和基体 (钛合金 )的相互关系 ,过渡层结构对该材料性能有重要影响。对界面的研究有助于更好的制备羟基磷灰石膜和研究羟基磷灰石在钛合金表面生长的机理。本文主要对基体、过渡层、羟基磷灰石做初步分析。过渡层上存在钛的一氧化物 ,羟基磷灰石的电镜照片与人骨的照片很相似。Hydroxyapatite seems to be the most suitable ceramic material for hard tissue replacement implants form the point of view of biocompatibility . Relation of ceramic and hydroxyapatite is important for it's performance. It will be useful for prepare the film of hydroxyapatite and the study of growing mechanism of hydroxyapatite on titanium. In this paper , titanium, layer of transition and hydroxyapatite are reviewed. There are T iO in the layer of transition, and hydroxyapatite is similar to human bone.
