Abstract:

Because the reliability and compatibility of spacecraft components is of utmost importance in propulsion systems, there is a need for accurate and, preferably, short-term evaluation techniques. 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.
