Nickel-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 Inprocess 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.
