Nikel titanium shape memory alloys (NiTi) are promising materials due to their shape memory effect. The disadvantage of the nickel is the toxicity, there are too many restrictions on the use of the human body. Hence, if the proper surface modification is chosen, the surface of NiTi can be tranquilized and smooth. Also, toxic chemicals can be protected by oxide film. The polishing method we have used is electro-polishing which is simple enough, economical and can handle wide range at once. In this study, we are surface modification NiTi by surface electro-polishing. The polishing method we have used is electro-polishing which is simple enough, economical and can handle wide range at once. We have used AFM(atomic force microscopy), SEM(scanning electron microscopy), OM(optical microscope) to analyze the roughness, and formation of surface of NiTi stent. To measure corrosion resistance, steady potentiostat was used to corrosion test. Our study group have concluded that condition of 40V 10seconds of electro-polishing showed the optimal stabilization of the surface.
