The adsorption of glycidoxypropyl‐trimethoxy‐silane (GTMS) on α and β phases of titanium alloy Ti–6.5Al–1Mo–1V–2Zr was studied. The morphology and composition of coated alloy were investigated by using field‐emission scanning electron microscopy, energy dispersive spectroscopy, and atomic force microscopy. The quantitative characterization of GTMS adsorption was carried out by using XPS. The results showed that the β phase particles exhibited better ability to adsorb GTMS molecules than the α phase, especially at lower concentrations of GTMS, which resulted in a relatively nonuniform silane coating. The differences in the adsorption ability between the α phase and β phase particles were attributed to the different alloying elements contained in them and different characteristics of the oxides formed on them. Uniform adsorption of GTMS on the overall metal surface was achieved by increasing the concentration of GTMS to 1 vol.%. Copyright © 2012 John Wiley & Sons, Ltd.
