摘　　要：采用喷砂处理对Ti6A l4V合金表面进行预处理,通过优化酸、碱浓度,处理方式,温度及时间等工艺参数在Ti6A l4V合金表面仿生生长HA涂层,利用SEM和XRD分析了涂层的形貌、物相以及结构,通过计算机模拟分析羟基磷灰石的生长机理。结果表明,经喷砂及草酸预处理,在Ti6A l4V合金表面形成了相对规整的窝洞,增加了羟基磷灰石的形核位置,通过优化工艺参数,最终在Ti6A l4V合金表面形成了类骨磷灰石层。The surface of Ti6Al4V alloy is treated by sand-blasting method,and the HA biomimetic coating is formed on Ti6Al4V alloy though the optimization of the process paramaters such as the consistence of acid and alkali,treatment method,temperature and time.The morphology,component and structure of the coatings are characterized by SEM and XRD.The mechanism of the biomimetic growth on the surface of Ti6Al4V alloy is simulated by computer analysis.The results indicate that the sand-blasting and pretreating for the surface can afford the more strength of the integration between the interfaces, and the biomimetic growth coating is the alike-ostein apatite.
