Weapon Systems and Technology Directorate Armament Engineering and Technology Center U.S. Army Armament Research, Development and Engineering Center., Document RTO-MP-AVT-109. 2004. -15 p.Wear and erosion – is one of several failure mechanisms that can cause large caliber Gun Barrels to be condemned and removed from service. This paper describes the phenomenon, its causes and effects, methods that are used to passively manage it, and steps that are taken to actively mitigate it.Contents:
