Abstract
A fabrication technique is described for producing lighter weight and improved wear and erosion resistant gun barrels. The barrels are produced in an unconventional manner from the inside bore to the outside diameter of the barrel and combine a refractory metal, metal alloy, or ceramic composite inner liner with a metal matrix composite (MMC) or titanium or other suitable high strength, lightweight metal or metal alloy outer shell. A unique aspect of the invention is that there is a compositional gradation from the liner at the inside bore to the overwrap which extends to the outside diameter of the barrel. A process is also described to produce barrels with a refractory metal liner with improved wear and erosion resistance by depositing the refractory metal on the ID of a pre-fabricated barrel.
