    Abstract: The present research looked at a passivation method for polished nitinol based implant and stent component after a standard heat setting treatment. Passivation of heat-treated samples in a nitric acid solution was followed by a series of corrosion tests, surface examination, and chemical analysis. The enhancement in corrosion resistance is suggeste... Show More
