CORROSION STUDIES ASSOCIATED WITH AN AIR BLAST CLOSURE UNIT
Abstract
To present the results of an eleven month exposure of an air blast closure unit(600 cfm army chemical center unit) to the marine atmosphere at Port Hueneme, and to make recommendations for changes in construction materials in order to reduce deterioration by corrosion and extend the operational life of the closure unit. The closure unit was inoperable after eleven months exposure in a marine atmosphere because of the formation of corrosion products. Various operational parts of the closure unit were cemented together by these corrosion products and the tension of the various small steel control springs had been destroyed. It is recommended that neoprene rubber gasketing be used throughout; that the louver door frame and support brackets be fabricated from 6061 Aluminum Alloy; that all pins be cadmium plated and coated with an inhibited soft grease such as AN-C-124a, AM3 Type II; and that all springs be heavily coated with the inhibited soft grease.
