Abstract Scope We studied formation of ceramic PEO coatings from aluminate-based electrolyte with KOH additives in 3, 4 and 5 g/l concentrations on the pure titanium substrate. The scanning electron microscopy (SEM) showed that the most compact and uniform PEO coating was formed with 4 g/l KOH additive, where despite increasing the number of porosities, the pore sizes declined. Due to excessive conductivity, the strongest sparks could form in electrolyte with 5 g/l KOH additive, which could cause creation of bigger pore sizes, and hence diminishing corrosion resistance. Using electrochemical impedance spectroscopy (EIS), we deduced PEO coatings with 4 g/l additive demonstrated the higher corrosion resistance with the best surface characteristics. X-ray diffraction analysis revealed a presence of TiAl2O5 phase with a mixture of rutile and anatase phases.
