Abstract:The corrosion fatigue strength of a TiNi shape memory alloy (SMA) is crucial for ensuring safety when the material is used as a sensor or actuator element in a severely corrosive environment, such as sea water. Furthermore, in the medical field, the corrosion fatigue strength in a blood vessel is important because it determines the product life of medical devices, such as self-expanding stents. In this study, we improved the corrosion fatigue strength of a TiNi SMA wire by electrolytic polishing. The main find… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
