Abstract
The plasma electrolytic oxidation of the titanium alloy OT4 was studied; the characteristics of the resulting coatings were determined–thickness, breakdown potential, corrosion current density, and X-ray phase; micro-X-ray spectral analysis was performed, and the morphology of the coatings was studied by scanning electron microscopy. We studied the effect of plasma electrolytic oxidation of OT4 and additional treatment of PEO coatings on the corrosion resistance of the aluminum alloy D16 (An.Ox.nchr, anodic treatment in chromate solutions) in contact with the titanium alloy in structurally similar samples.
