Explosion Bonding is Golden!

Explosion bonding as a process recognized for its potential for commercial application is celebrating its 50th anniversary in 2010. In 1960, two patent applications were filed which recognized and described the explosion bonding process for its ability to join or bond metals. These two patents were the result of accidental discoveries and subsequent developmental work in the late 1950s. The first application was filed on August 31, 1960 by Phillipchuk and Bois and assigned to Atlantic Research Corporation (Patent No. 3,024, 526). The second was filed on October 26, 1960 by Cowan, Douglass and Holtzman and assigned to E.I. du Pont (Patent No. 3,137,937). The Cowan, et. al. patent was more inclusive and ultimately took precedence in the United States. It was commercialized by du Pont in the early 1960s. The phenomenon of explosion or high velocity impact bonding of metals, however, is much older than 50 years. Stay tuned for more info.
