用离子束混合法在Ti-6Al-4V钛合金表面沉积碳膜。X射线光电子能谱分析表明，混合后，表面膜基本上由含（Ti，O和C），TiO 2，Ti和C污染的Ti化合物组成。用卢瑟福背散射光谱法测定了表面改性膜的成分为Ti_（0.5）O_（0.3）C_（0.2），膜厚约为200 nm.在模拟体液中浸泡3个月后，观察到了含有HPO_4 ~-和H_2 PO_4 ~-的磷酸钙物种（可能是CaHPO_4和Ca（HPO_4）（2））的生长.钛被发现基本上是由钛化合物浸渍后，这表明金属Ti和TiO 2已溶解。(C)1997年爱思唯尔科学有限公司。All rights reserved.
Surface of titanium alloy (Ti-6Al-4V) has been modified by ion beam mixing of thin C film. X-ray photoelectron spectroscopy analysis showed that after mixing, the surface film consists essentially of a Ti compound containing (Ti, O and C), TiO2, Ti and C contamination. The composition of the surface modified film determined by Rutherford backscattering spectrometry is approximately Ti0.5O0.3C0.2 and its thickness is about 200 nm.After three months immersion in a simulated body fluid, the growth of calcium phosphate species containing both HPO4- and H2PO4- (probably CaHPO4 and Ca(HPO4)(2)) have been observed. Titanium is found to be essentially composed of the Ti compound after immersion suggesting that both metallic Ti and TiO2 have dissolved. (C) 1997 Elsevier Science Limited. All rights reserved.
