To seek a new method of titanium passive treatment by combined anodic oxidation and thermal air treatment, which could increase the corrosion resistance and biocompatibility of pure titanium.
Characteristics of Titanium sheets with natural oxide film (NOF), anodic oxide film (AOF), or heated anodic oxide film (HAOF) were compared and tested by x-ray diffractrometer, electrochemical corrosive method, and contact angle device.
HAOF had excellent corrosion resistance and greater crystallinity, indicating the crystal structure had changed. AOF had better hydrophily.
This in vitro study showed that thermal air treatment, after anodic oxidation, was a reliable method for creating a passive, protective film on the titanium surface, which could greatly enhance the corrosion-resistance and crystallinity.
探寻一种通过阳极氧化与热空气处理相结合的钛钝化处理新方法,以提高纯钛的耐腐蚀性和生物相容性。
采用X射线衍射仪、电化学腐蚀法和接触角测量仪,对具有天然氧化膜(NOF)、阳极氧化膜(AOF)或加热阳极氧化膜(HAOF)的钛板特性进行比较和测试。
HAOF具有优异的耐腐蚀性和更高的结晶度,表明晶体结构发生了变化。AOF具有更好的亲水性。
这项体外研究表明,阳极氧化后的热空气处理是在钛表面形成钝化保护膜的可靠方法,可大大提高耐腐蚀性和结晶度。
