Endothelium Cell Responses on Pulsed-Anodized NiTi Alloy with HNO<sub>3</sub>, NH<sub>4</sub>NO<sub>3</sub>, H<sub>2</sub>SO<sub>4</sub>, and (NH<sub>4</sub>)<sub>2</sub>SO<sub>4</sub> as Electrolytes
Abstract:Pulsed anodization allows to form a Ni-free TiO 2 layer on an almost equiatomic NiTi alloy. The surface is then hydrophilized and impedes the release of Ni ions from the alloy. This study aimed to assess the suitability of electrolytes used in the pulsed anodization process with the view of application as a biomaterial. Toward this end, the NiTi alloy was pulsed-anodized in four different aqueous electrolytes, HNO 3 , NH 4 NO 3 , H 2 SO 4 , and (NH 4 ) 2 SO 4 , after which the endothelium cell behavior was com… Show more
