摘要： A multi-layer composite gun barrel has an integral metal alloy jacket portion, forming the exterior cylinder of the entire barrel, with a forebarrel interior liner cylinder substantially bonded within the jacket portion, and an unbonded breech portion liner, made from a high melting temperature refractory metal alloy able to resist erosion by hot gun gases in the barrel breech area.

摘要： The present invention provides a gun capable of operating at relatively higher temperatures. The barrel of the gun is made up of at least two layers. The inner layer is of a refractory material which may be a metal refractory or a non-metal refractory. The liner is bonded to an outer jacket material formed of an alloy of nickel, aluminum and molybdenum. The coefficient of expansion of the liner and of the jacket are relatively low so that the gun does not expand extensively when heated by intensive use. The jacket metal is of higher strength at elevated temperature than is the conventional gun barrel steel.

摘要： 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.
