Resumen

A dense alumina ceramic coating was formed on UNS A97075 Al alloy by plasma electrolytic oxidation (PEO). An efficient and environmentally friendly silane layer was prepared to seal the PEO coating. The scanning electron microscopy (SEM) results showed that the PEO coating was completely sealed by the silane layer. The electrochemical corrosion evolution of the silane sealed PEO composite coating was studied by electrochemical impedance spectroscopy (EIS). Based on the EIS data, the corrosion evolution of the silane sealed composite coating could be divided to three stages during 576 h of immersion test, and the silane coating acted as a good physical barrier in the immersion test, effectively delayed the corrosion process and improved the corrosion resistance.
