Nitinol as a superelastic alloy has become an ideal material for use as self-expanding stents grafts and other support systems due to is excellent superelasticity biocompatibility and corrosion resistance. In terms of corrosion resistance many studies have focused on the effects of surface treatments oxide thickness strain and presence of contaminants. However in addition to these issues a cardiovascular stent will also see the effect of flow of blood through the artery. Thus this work assessed the effects of fluid flow on the corrosion behavior of a superelastic Nitinol alloy. Electrochemical potentials were obtained on the Nitinol material while under flow conditions with a simulated body fluid. Short term and long term effects were addressed. Post test surface appearance was documented by Scanning electron microscopy (SEM). The surface oxide layer was characterized by AES. Comparison of surface properties between stagnant and flow conditions are discussed.
