摘　　要：目的:碱热法和热有机膜法预处理后在镁合金表面仿生制备羟基磷灰石涂层的研究。方法:采用碱热法和热有机膜法对镁合金进行预处理,然后将其浸泡在仿生溶液中制备羟基磷灰石涂层。结果:热有机膜处理后的镁合金,其羟基磷灰石的沉积速度和结晶度都优于碱热法。结论:热有机膜法预处理镁合金能更好的制备羟基磷灰石涂层。Objective： To study preparation of hydroxyapatite （HA） coat on magnesium alloys in biomimetic synthesis by alka- li-heat treatment and heat-organic layers treatment techniques. Methods： Magnesium alloys were pre-treated by the alkali-heat treatment and heat-organic layers treatment and then soaked in biomimetic synthesis to prepare hydroxyapatite coat. Results： The deposition rate and crystallinity of HA treated by the heat-organic layers treatment were better than those by alkali-heat treatment. Conclusions： Using heat-organic layers to pre-treat magnesium alloys can better prepare HA coat.
