对用溶胶－凝胶法（简称Ｓｏｌ－Ｇｅｌ）多次重复涂层烧结ＨＡ－Ｔｉ复合种植体的工艺条件进行了探索性研究，使多层超细ＨＡ涂层粉末的纯度、结晶度和ＨＡ晶体的纳米结构得到改善，还能使涂层与基底材料各组分相互混合达到分子水平的均匀，并在界面生成牢固的化学过渡层。Ti
The process conditions of HA-Ti composite implant sintered repeatedly by sol-gel method (hereinafter referred to as Sol-Gel) were explored to make the purity, crystallinity and HA of multi-layer HA coating powder Crystal nano-structure is improved, but also make the coating and base material components mixed with each other to reach a molecular level uniform, and in the interface to generate a solid chemical transition layer.
