Abstract:
Since a fire suppressant which is corrosive to either
the materials used for storage and distribution of the
agent or to aircraft materials after deployment would be
undersirable, experiments were conducted to assess the
relative corrosivity of the potential fire suppressants
to different metallic alloys used on aircraft. These
experiments were designed to evaluate the propensity of
the different agents to cause failure by any of the
possible corrosion failure modes during service or after
deployment. In addition to these experiments,
experiments were conducted to develop an electrochemical
technique that would rapidly, and less expensively,
evaluate the corrosivity of an agent and the influence
of changes in composition, temperature and contaminant
levels on the corrosivity of an agent.
