Surface of titanium alloy (Ti-6AI-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.
钛合金（Ti-6AI-4V）表面已通过薄碳膜的离子束混合进行了改性。X射线光电子能谱分析表明，混合后表面膜主要由含有（Ti、O和C）的Ti化合物、TiO₂、Ti和C污染物组成。通过卢瑟福背散射光谱法测定的表面改性膜的组成约为Ti₀.₅O₀.₃C₀.₂，其厚度约为200纳米。在模拟体液中浸泡三个月后，观察到含有HPO₄⁻和H₂PO₄⁻（可能是CaHPO₄和Ca(HPO₄)₂）的磷酸钙物种的生长。浸泡后发现钛主要由Ti化合物组成，这表明金属Ti和TiO₂都已溶解。
