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.
