摘要(Abstract)：

首先在钛板表面进行飞秒激光和阳极氧化处理，测试其摩擦学性能。然后选取4种牙科常见的材料分别涂覆在钛板表面后进行飞秒激光和阳极氧化处理，观察各试样表面微坑精度及微坑周缘涂层材料的边缘封闭性和稳定性。结果表明：钛板经过处理后的耐磨性能较好，适用于人体环境。选用的4种材料均容易涂覆和去净。其中，液体硅胶和牙科用弹性体印模材料不影响激光加工精度，牙科用蜡和聚四氟乙烯薄膜影响较大，且蜡会混入微坑内。液体硅胶和蜡涂层具有稳定性和边缘封闭性，而牙科用弹性印模材料和聚四氟乙烯薄膜容易松动脱落，无法对非加工区进行隔离。因此液体硅胶是比较理想的可以对钛材表面非加工区隔离保护的材料。

关键词(KeyWords)： 钛板;飞秒激光;阳极氧化;非加工区;摩擦学性能;隔离保护
