In this study, electrochemical impedance spectroscopy has been used to determine the corrosion rates of metals in liquid hydrazine. The electrochemical information was obtained in a relatively short time (hours) and the corrosion rates thus derived compared favorably with those obtained from the classical, real-time method. 收起
