为了了解钛和生物组织之间的界面现象，使用X射线光电子能谱（XPS）检查了电解溶液中钛上形成的表面膜。钛浸入溶液前表面膜的成分接近于TiO2，而Ti-6 Al-4 V的成分是TiO2和Al2O3的混合物。当样品浸入电解溶液中时，这些表面薄膜会变成含有羟基自由基和水合物的钛和钙复合磷酸盐。钛和Ti-6 Al-4 V表面膜的成分几乎相同，只是Ti-6 Al-4 V表面膜比钛更厚且含有更多的水合物。 Ti-6 Al-4 V 中的钒以及溶液中的钠、氯和硫对薄膜的形成没有影响。
In order to understand the interface-phenomena between titanium and biological tissue, the surface film formed on titanium in electrolytic solutions was examined using X-ray photoelectron spectroscopy (XPS). The composition of the surface film on titanium before immersion into solution is close to TiO2 and that of Ti-6 Al-4 V is a mixture of TiO2 and Al2O3. These surface films change to a complex phosphate of titanium and calcium containing hydroxyl radicals and hydrates when the specimens are immersed in an electrolytic solution. The compositions of the surface films of titanium and Ti-6 Al-4 V are almost the same except that the film on Ti-6 Al-4 V is thicker and contains more hydrates than that on titanium. Vanadium in Ti-6 Al-4 V, and sodium, chlorine, and sulfur in the solution are not responsible for the formation of the films.
