The present work focuses on the effect of Ni content (0, 5, 10, and 30 %) on the corrosion behavior of Cu-10Al-xNi ternary alloys in Na 2 SO 4 solutions.The electrochemical properties were investigated in Na 2 SO 4 solutions by polarization measurements, cyclic voltammetry and electrochemical impedance spectroscopy, EIS, techniques.Surface examination and morphological studies were employed.The re...
