Binary munitions in which two different constituents are kept in separate compartments until activation will constitute a significant fraction of the chemical weapons in the United States. Because these munitions will be used under extreme circumstances, they must be stockpiled over very long periods of time (up to 30 years) and still be able to operate reliably when the need arises. A very high reliability of the storage container is essential to the subsequent activation of, and availability of, this weapon system. Electrochemical potentiodynamic polarization studies have been carried out for a variety of ferrous and nonferrous metals in methylphosphonic difluoride. Studies of the effect of organic inhibitors on the corrosion rate of 1020 steel (UNS G10200), 316L (UNS S31603), and 304 stainless steel (UNS S30400) and magnesium in methylphosphonic difluoride were also carried out. In addition, electrochemical studies were conducted in decontaminating solutions of sodium carbonate, organic/hydroxide and bleach. General corrosion rates are reported for ferrous alloys, titanium, aluminum alloys, magnesium, and two metal-matrix composites in full strength and diluted decontaminating solutions.
