Formation of bioactive coatings on a Ti–6Al–7Nb alloy by plasma electrolytic oxidation

In an attempt to increase the bioactivity and corrosion resistance of a vanadium-free titanium alloy Ti–6Al–7Nb, the electrolytic plasma oxidation (PEO) process for surface modification was utilised. Select samples were subjected to further treatment, either thermal or alkali. The morphology, chemical composition and phase composition of the ground and treated Ti–6Al–7Nb alloy substrates were investigated using scanning electron microscopy...
