Evaluation of the Corrosion Behavior of Storage Container Alloys in Halon 1301 Replacement Candidate Agents, Tri-Service Conference on Corrosion Proceedings,
Abstract
The Montreal Protocol of 1987 identified a number of halogenated chemicals which possess sufficient stratospheric ozone depletion potentials to warrant limitations on their production and use. Included on this list was Halon 1301 (CF3Br), the fire suppression agent of choice for aircraft engine nacelles and dry bays (1). As a result, the relative performance of different chemical compounds with low ozone depletion potentials were evaluated as a CF3Br fire suppressant replacement. Since corrosion of fire suppressant containers by the agent could affect the reliability of these vessels, the corrosion behavior of typical alloys used in these containers needed to be evaluated. Mass change tests were performed for 1 month in different agents at 150 deg C. Electrochemical tests were desired to supplement and possibly replace the current mass change experiments. A major advantage of electrochemical testing is the significant reduction in time required to estimate corrosion rates and the effect that pollutants (HF, HCl, and H2O) in various agents, compositional changes, and the temperature have on the corrosion rate.
