Electrochemical behavior of additively manufactured patterned titanium alloys under simulated normal, inflammatory, and severe inflammatory conditions

The electrochemical behavior of a biomaterial surface in local conditions is significant factor affecting the success implant placement. This particular importance metallic biomaterials which can undergo oxidation, corrosion and subsequent degradation. study reports new data on additively manufactured (AM) patterned titanium alloys, analyzed after 1 12 h immersion three different media mimicking normal, inflammatory severe conditions. Polarization showed that resistance increases with increasing time all cases. It was found condition destructive effect passive layer's triggered by H2O2 whereas condition, albumin, lactate, have synergistic towards decreasing layers. Electrochemical impedance suggests charged albumins are attracting to localized pitting areas, changing diffusion transport corrosive species at interface metal/passive layer. tests also proven laser-assisted alloys surfaces an improved simulated solutions compared untreated same composition. suggested topography wettability positive factors contributing this performance specimens.
