| Abstract | |
In the present work, the effects of Gd, Mn, and Sn additions on the surface chemistry and the electrochemical behavior of CuAl-based shape memory alloys were studied. Alloys were produced by arc furnace melting. The corrosion behavior was evaluated by electrochemical impedance spectroscopy (EIS) in 3.5 wt% NaCl solution up to 24 h of immersion. The surface chemical states were assessed by X-ray photoelectron spectroscopy (XPS). Correlation between the corrosion behavior and the surface chemistry is discussed. Gd addition increased the corrosion resistance of the CuAl-base alloy. Mn and Sn additions led to the formation of non-protective oxide films. (AU) | |
