Corrosion behaviors of the NiTiCu shape memory alloys wire were investigated by electrochemicaltechniques in physiological environments of Ringer solution. Three measurements were conducted; mainly opencircuit potential (OCP) measurement, linear polarization, and cyclic polarizations. The results showed that passivefilm formation on quenching NiTi alloy was formed faster than that on aging NiTiCu. The quenching NiTi alloy wireexhibits more negative corrosion potential and higher corrosion current than aging NiTiCu does. Cyclicpotentiodynamic of two NiTiCu samples show similar pattern. Pitting corrosion of quenching NiTiCu occurs athigher potential than aging NiTiCu.
