Abstract:

For tank cannons, the battlefield demands for increased muzzle velocity and lethality have resulted in wear life reduction of the barrel. Cylindrical magnetron sputtering is being developed as a new, environmentally friendly bore coating process for large caliber cannons. This paper discusses how, in general, the process is being applied and describes how technology maturation is being achieved. Obtaining acceptable adhesion has been the greatest technical challenge encountered. Specific enabling technologies to improve coating adhesion are discussed.
