Actuators loaded with Ti/KC1O/sub 4/ and aged for several days had chlorine-containing corrosion products on Alloy-52 electrode pins and Tophet-C bridgewire surfaces. An in-depth analysis of these materials indicated that moisture, organic contamination, and chlorine were the major causes of the corrosion. Definite evidence was uncovered that indicated a partial decomposition of the KC1O/sub 4/ was the major source of the chlorine. In the presence of moisture, particles that settle on the metal surface cause the formation of galvanic or oxygen concentration cells that dissolve to produce electrolytes on the metal surface causing corrosion of the metal.
