Electrochemical Response in Biological Media of Plasma Electrolytic Oxidation Treated Additively Manufactured Ti6Al4V Alloy

Innovative 3D metal additive manufacturing (AM) techniques are revolutionizing the biomedical industry, since they enable production of porous structures and patient-customized parts biomedical-grade materials, such as Ti alloys. Surface treatment via plasma electrolytic oxidation (PEO) conventionally manufactured its alloys has been proved an outstanding approach to promote osseointegration implants. Henceforth, it is increasing interest develop PEO treatments for AM The objective present work was fabricate Ca P containing thin (~3–10 μm thickness) coatings on a Ti6Al4V alloy direct laser sintering (DMLS), powder bed fusion technique, study electrochemical behavior treated specimens in modified α-MEM solution. electrical response process compared that wrought mill-annealed sheets. PEO-treated evaluated potendiodynamic polarization impedance spectroscopy (EIS) comparison non-treated conventional counterparts. surface degradation morphologies were by electron-optical microscopy optical profilometry. effect microstructure resultant discussed with aim define future research directions relevant improvement corrosion resistance Ti6Al4V, particularly regard pitting corrosion.
