%X The corrosion behavior of Cu-Zn-Al shape memory alloys (SMA) with and without electroless nickel plating was investigated by electrochemical methods in artificial Tyrode's solution.The results showed that Cu-Zn-Al suffered from engendered dezincification corrosion in Tyrode's solution.The anodic active current densities as well as electrochemical dissolution sensitivity of the electroless nickel plated Cu-Zn-Al SMA increased with the increasing NaCl concentration,decreasing pH value and rising temperature of the solution.X-ray diffraction analysis indicated that after electroless nickel plating,an amorphous film formed on the surface of Cu-Zn-Al SMA.This film can effectively isolate the matrix metal from corrosion media and significantly improve the corrosion resistance of the Cu-Zn-Al SMA in artificial Tyrode's solution.
