Sažetak
The corrosive behaviour of Cu-Al-Ni shape memory alloy in deaerated 0.5 M NaCl solution at 20 ºC was studied by means of open circuit potential measurements, linear polarization, potentiodynamic polarization measurements, cyclic voltammetry and electrochemical impedance spectroscopy measurements. The electrode surface was examined by light microscope, SEM and EDX microanalysis. The polarization measurements have shown that corrosive behaviour of Cu-Al-Ni alloy in NaCl solution was dominated by the Cu component. The results of impedance measurements at open circuit potential have shown that the overall impedance of the system increases with immersion time due to continuous growth of the passive film on the alloy surface. The SEM and EDX microanalysis showed the presence of copper, aluminium and nickel oxides and chlorides on alloy surface.
