Sažetak
CuAlNi alloy has been evaluated for its corrosion behaviour in the 0.5 mol dm-3 H2SO4 stirred solution at the rotation rate of magnetic stirrer of 150 and 450 rpm, at 20 and 40 oC. Investigations were performed using open circuit potential measurements, linear and polarization measurements. After polarization measurements corroded surfaces were evaluated using light microscopy analysis. It was found that increasing in electrolyte temperature leads to higher corrosion damages of alloy while increase in rotation rate of stirrer has smaller impact on corrosion. The presence of intergranular corrosion on the electrode surfaces was clearly seen with optical microscope.
