The Corrosion of Metals in Aqueous Film-Forming Foams.
Abstract
A research program was initiated primarily to investigate the corrosion susceptibility of Type 304 stainless steel shipboard firefighting systems to aqueous film-forming foam (AFFF) concentrate. Subsequently, other candidate alloys for use in such systems were also studied. To assess corrosion behavior a special laboratory technique was devised with which localized corrosion was stimulated by an intentional crevice. Weight-loss measurements, surface examination techniques, and potentiostatic polarization studies were utilized also to determine the effects and relationships of media pH and chloride-ion content on corrosivity. The results of these studies indicate that the synergetic effects of low pH and high chloride-ion content caused accelerated localized attack in Type 304 stainless steel. This high degree of corrosivity was not evident in the AFFF (200) series formulation. (Author)
