Bioactive coatings were obtained via the sol gel method and deposited onto AISI 316L stainless steel by pneumatic spray. TEOS and MTES were used as precursors to obtain a hybrid sol in which wollastonite bioactive particles were dispersed. The corrosion resistance of the coatings was studied with the aid of potentiodynamic curves after immersion of the coatings in SBF (simulated physiologic fluid) for 7 and 40 days. The thickness of the coatings was 47.7 ± 8 µm, as measured from SEM images. In comparison with other methods of deposition, with the pneumatic spray technique it was possible to obtain thicker coatings, giving the substrate a better protection factor against corrosion. After immersion in SBF, formation of an apatite film on the surface and inside the pores was observed, which helps promote osseointegration and improve corrosion resistance of the substrate. These coatings could be used in metallic implants whose bioactivity and corrosion resistance need to be improved.
