Passivation and Depassivation of Alloy 22 in Acidic Chloride Solutions

Alloy 22 (N06022) is a Ni–Cr–Mo alloy that offers an outstanding corrosion resistance in a wide variety of highly corrosive environments. In the present work, the general corrosion of alloy 22 in the passive and active states and the transition from passive and active states were studied in acidic chloride solutions at . Electrochemical studies, including electrochemical impedance spectroscopy and polarization tests, were performed using...
