Abstract
Nikel-Titanium (Ni-Ti) alloy is known for its shape memory properties. These properties are useful for various biomedical applications. However, a high percentage of nickel elements in Ni-Ti alloy elicit toxicity, allergic responses, and limits practical uses of the alloy. Therefore, further improvement of the corrosion resistance of Ni-Ti alloy is desirable for implant applications. In this study, the authors conducted a study by using Ni-Ti alloy on the new compound surface modification method consisting of a new electrical grinding technique (EG-X) based on ELID (Electrolytic In-process Dressing) grinding and Thermal Oxidation (TO). The results showed that the new compound surface modification method can achieved high quality surface compared with the conventional TO treated surface.
