【摘要】 本文应用XPS技术对三组不同温度热氧化处理钛种植体的表面进行了分析，三种表面分别为：自然氧化组（即商业纯钛），人工氧化组（400℃，45分钟）和高温氧化组（700℃，45分钟）。发现三组钛试样表面的主要化学元素和组咸均相同，并且随着氧化温度的提高表面氧的相对含量提高，而碳的相对含量变化不大。通过对表面钛、氧、碳三种元素的详细分析可确定它们的化学状态，获得TiO2、TiO、0－2和O2在不同深度的分布状态并得出了规律。还用XPS测得了在不同温度和时间下氧化后钛表面氧化膜的厚度。从总体分析情况推荐人工氧化表面组作为最适宜的种植体表面状态。更多还原

【Abstract】 In this paper, the surfaces of titanium implants under three different kinds of thermal treatments were in-vestigated using XPS techniques. The treamients were: natural - oxidation(c. p. Ti), artificial - oxidation(380 ℃ , 45min), high temperature oxidation(700℃ , 45min). It was discovered that the main chendcal ele-ment and composition of the three groups of titanium surfaces were the same, while in the surfaces the relativeamount of oxygen increased and that of titanium decreased with oxidation temperature increasing and that ofcarhon had no obvious relation to oxidation temperaure. Through detailed analysis of titanium(Ti2p), oxygen(01s) and carbon(Cls) in the surfaces, their chemical states were detendned. The distribution states ofTiO2, TiO, 02 and 0 -2 at different depth were obtained and the general law were concluded. From overallanalysis, artificial - oxidation surface group was recommnded as the most siutable surface state of implant更多还原
