Notes:
TiO2 coatings on titanium alloy substrates were prepared by atmospheric plasma sprayingusing commercial nano-powders and followed by H2SO4 treatment. The bioactivity of coatings wasevaluated by the simulated body fluid soaking test. Scanning electron microscopy andenergy-dispersive X-ray spectrometry were used to characterize the surface morphologies and phasecomposition of the coating before and after soaking in simulated body fluid. The results obtainedindicate that H2SO4-treated TiO2 coating can induce a bone-like apatite formation on its surface,however, no apatite appears on the surface of as-sprayed TiO2 coatings. The acid concentration andtreated time affected the bioactivities of TiO2 coatings
