Hygrothermal Aging Effect on Firing and Corrosion Behavior of Fuse-Head Used for Electric Explosive Device

Temperature and humidity are critical environmental factors that can be damaging the structure of electric explosive device. In this paper, experimental studies were presented to appreciate the influence of humidity and temperature on the corrosion damage and firing of electric explosive device. The explosive broken and corrosion damage on lead induced by hygrothermal aging were the main factors affecting the firing probability. At last, the evolution rule of corrosion weight loss in the environment of different relative humidity and temperature was discussed.
