Electrochemical Test Method for Evaluating Long-Term Propellant-Material Compatibility
Abstract
An electrochemical technique for evaluating the long-term compatibility of liquid propellants in various containment materials is described. The method requires that the liquid and containment material be electrical conductors, that the exchange current be measurable, and that the propellant decomposition mechanism be known. The time base is then altered by electrolysis of the system at some multiple of the natural decomposition rate. As a result, a simulated time scale is achieved in which the propellant decomposition rate can be predicted up to fifteen years while the actual time required for the tests is on the order of one to two months, depending on the particular metal tested.
