To investigate the impact of CoSO 4 on Ti6-Al4-V titanium alloy plasma electrolytic oxidation coatings and their erosion resistance, was performed in electrolytes with varying concentrations. Scanning electron microscopy, XRD, XPS, electrochemical workstations, corrosion testers were used to study effects morphology, phase composition, properties coatings. Results indicated that increasing concentration led higher voltages, fewer micropores microcracks, a more uniform dense surface. The mainly consisted Ti, Anatase, Rutile, CoO phases. best overall performance achieved 0.8 g L −1 , where self-corrosion current density decreased from 1.04 × 10 −7 A cm −2 (substrate) 2.21 −8 indicating enhanced resistance.
