【摘要】：为克服纯钛种植牙硬度低,在维护保养过程中表面易被划伤的问题,在纯钛表面制备了高硬度渗氮钛(TiN)陶瓷层;在不降低TiN硬度的前提下,采用水热处理方法对TiN进行部分氧化处理,以改善其骨传导性。结果表明,水热处理温度不超过100℃时,TiN表面发生部分氧化,润湿性能得到改善,而表面形貌及硬度未发生变化;当水热处理温度高于100℃时,试样表面出现纳米尺寸沉积,硬度明显下降;100℃是在去离子水介质中对TiN进行水热处理的临界温度。水热处理在对TiN进行氧化的同时能够保持其高硬度,可以使TiN成为优良的种植牙镀层材料。
[Abstract]:In order to overcome the problem of low hardness and easy scratching on the surface of pure titanium implant teeth, a high hardness nitrided titanium tin (TiN) ceramic layer was prepared on the surface of pure titanium, and the hardness of tin was not reduced. Tin was partially oxidized by hydrothermal treatment to improve its bone conductivity. The results show that the surface of tin is partially oxidized, the wettability can be improved, but the surface morphology and hardness are not changed when the hydrothermal treatment temperature is less than 100 鈩，
