Abstract
A gun barrel is produced by vacuum plasma spray depositing an inner layer of a refractory metal as a gun barrel liner on a mandrel, followed by deposit of successive layers of dense gun barrel jacket material to build up a structure from the inside out. The outermost layer can include attachment means for fixing the barrel into a gun mechanism.
