Abstract

Effects of anodic oxidation in H₂SO₄ electrolyte on the biocompatibility of NiTi shape memory alloy (SMA) were investigated by characterizing surface structure, blood compatibility, wettability, release of harmful Ni ions of anodized NiTi SMA. Although titania film resulting from anodic oxidation in H₂SO₄ electrolyte has a porous structure, it can effectively block out-diffusion of Ni from NiTi SMA to simulated body fluid (SBF). Comparing with chemical polishing, anodic oxidation in H₂SO₄ electrolyte can also improve the wettability, blood compatibility, thromboresistance of NiTi SMA. © 2008 Elsevier B.V.
