Sažetak
Shape memory alloys are usable in numerous areas. The effect of the shape memory alloys is basically a recollection on a former deformation of the applied form of the material. In the physical sense, it is a byproduct of the martensite phase transformation in the structure of the homogenous matter. Microstructural analysis of Cu-Al-Ni alloy before corrosion testing was carried out by optical and scanning electron microscopy, respectively. The corrosion behaviour of Cu-Al-Ni shape memory alloy in deaerated 0.5 M NaCl solution at 20 ºC was studied by means of polarization measurements. Surface morphologies of selected specimens after corrosion testing (at -0.2V and 0.4V) were investigated by optical microscope, SEM and EDX microanalysis. The polarization measurements have shown that the corrosion behaviour of Cu-Al-Ni alloy in NaCl solution was dominated by the Cu component. The SEM and EDX microanalysis showed the presence of copper, aluminium and nickel oxides and chlorides on alloy surface.
