Abstract
A method of forming a gun barrel is disclosed that includes applying one or more coatings to the gun barrel such as just a top coating, or a bond coating and then a top coating. The method may also include (before applying one or more coatings): threading an outer surface of the gun barrel proximate a first end of the gun barrel; threadedly coupling the first end of the gun barrel to a gun chamber; fixedly coupling the gun barrel to the gun chamber. The method may also include heat treating the coating layer(s), contouring the outer coating layer, applying a ceramic top coating to the contoured outer coating layer of the gun barrel, and/or sealing the gun barrel with a liquid metal sealer.
