中文摘要
针对钛合金植入体生物活性氧化钛薄膜处理工艺链长的问题，探讨利用加工的方法得到所要求的氧化膜厚度的方法。实验分为3组,即自然条件下车削加工、富氧气氛下车削加工和富氧气氛下滚压加工，并对其表面氧化膜的厚度和表面形貌进行观测。结果表明：富氧气氛下滚压加工表面得到的生物活性氧化膜厚度达1 558 nm，约为富氧气氛下车削加工表面氧化膜厚度（456 nm）的3.4倍，是自然条件下车削加工表面氧化膜厚度（49 nm）的31倍。富氧气氛下滚压加工表面得到的钛合金氧化膜厚度能够达到植入体的植入要求。滚压加工表面出现不规则的微纳结构的表面形貌，增加了植入体的表面能，有利于细胞的早期黏附。
英文摘要
The oxide film on the surface of titanium alloy is important to osseointegration.A new method was proposed to obtain required titanium oxide film during machining or forming process.Experiments were conducted which include turning in natural atmosphere,turning in oxygen-enriched atmosphere and rolling in oxygen-enriched atmosphere.The thicknesses of titanium oxide film were tested and surface topographies were observed respectively.Results showed that the thicknesses of titanium oxide film are 49 nm,456 nm and 1 558 nm in these three conditions.It proved that rolling after turning in oxygen-enriched atmosphere can obtain the required film thickness,also the micro/nano topography of is helpful to cell adherence.
