A method of forming a gun barrel from a gun liner is disclosed that includes applying one or more coatings to the gun barrel liner 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 liner proximate a first end of the gun barrel liner; threadedly coupling the first end of the gun barrel liner to a gun chamber; fixedly coupling the gun barrel liner 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 liner, and/or sealing the gun barrel with a liquid metal sealer.

1. A method of manufacturing a gun barrel comprising: threading an outer surface of a gun barrel liner proximate a first end of the gun barrel liner;threadedly coupling the first end of the gun barrel liner to a gun chamber;fixedly coupling the gun barrel liner to the gun chamber; andapplying one or more coatings to the gun barrel liner, wherein applying one or more coatings comprises: cold gas-dynamic spraying the gun barrel liner with a top coating comprising at least one of titanium powder, titanium alloy powder, aluminum powder, aluminum alloy powder, titanium-aluminum matrix powder, chromium powder, chromium alloy powder, cobalt powder, cobalt alloy powder, iron powder, iron alloy powder, nickel powder, and nickel alloy powder; orapplying a bond coating comprising a nickel based alloy or superalloy to the gun barrel liner; and then cold gas-dynamic spraying the gun barrel liner with a top coating comprising at least one of titanium powder, titanium alloy powder, aluminum powder, aluminum alloy powder, titanium-aluminum matrix powder, chromium powder, chromium alloy powder, cobalt powder, cobalt alloy powder, iron powder, iron alloy powder, nickel powder, and nickel alloy powder. 2. The method of claim 1, further comprising threading an inner surface of the gun chamber complementary to the threaded outer surface of the gun barrel liner. 3. The method of claim 1, wherein fixedly coupling the gun barrel liner to the gun chamber comprises at least one of tack welding, soldering, or brazing the gun barrel liner and the gun chamber. 4. A method of manufacturing a gun barrel comprising: applying a bond coating comprising an alloy or superalloy to a gun barrel liner; andcold gas-dynamic spraying the gun barrel liner with a top coating comprising at least one of titanium powder, titanium alloy powder, aluminum powder, aluminum alloy powder, titanium-aluminum matrix powder, chromium powder, chromium alloy powder, cobalt powder, cobalt alloy powder, iron powder, iron alloy powder, nickel powder, and nickel alloy powder. 5. The method of claim 4, wherein applying the bond coating comprises applying a bond coating comprising a nickel based alloy or superalloy to the gun barrel liner. 6. The method of claim 5, wherein applying the bond coating comprises spraying the gun barrel liner with a bond coating comprising a nickel based alloy or superalloy. 7. The method of claim 6, wherein spraying the gun barrel liner comprises thermal spraying the gun barrel liner with a bond coating comprising a nickel based alloy or superalloy until the bond coating is between approximately 0.005 inches and 0.010 inches thick. 8. The method of claim 6, wherein cold gas-dynamic spraying the gun barrel liner comprises cold gas-dynamic spraying the gun barrel liner with the top coating until the bond and top coatings together are between approximately 0.300 inches and 0.500 inches thick. 9. The method of claim 4, further comprising: threading an outer surface of the gun barrel liner proximate a first end of the gun barrel liner;threadedly coupling the first end of the gun barrel liner to a gun chamber; andfixedly coupling the gun barrel liner to the gun chamber before applying the bond coating. 10. The method of claim 9, further comprising threading an inner surface of the gun chamber complementary to the threaded outer surface of the gun barrel liner. 11. The method of claim 9, wherein fixedly coupling the gun barrel liner to the gun chamber comprises at least one of tack welding, soldering, or brazing the gun barrel liner and the gun chamber. 12. The method of claim 4, wherein applying a bond coating comprises thermal spraying the gun barrel liner with a bond coating comprising a nickel based alloy or superalloy until the bond coating is between approximately 0.005 inches and 0.010 inches thick. 13. The method of claim 4, wherein cold gas-dynamic spraying the gun barrel liner comprises cold gas-dynamic spraying the gun barrel liner with the top coating until the bond and top coatings together are between approximately 0.300 inches and 0.500 inches thick. 14. The method of claim 4, further comprising heat treating the bond and top coatings. 15. A method of manufacturing a gun barrel comprising: cold gas-dynamic spraying a gun barrel liner with a top coating comprising at least one of titanium powder, titanium alloy powder, aluminum powder, aluminum alloy powder, titanium-aluminum matrix powder, chromium powder, chromium alloy powder, cobalt powder, cobalt alloy powder, iron powder, iron alloy powder, nickel powder, and nickel alloy powder. 16. The method of claim 15, further comprising: threading an outer surface of the gun barrel liner proximate a first end of the gun barrel liner;threadedly coupling the first end of the gun barrel liner to a gun chamber; andfixedly coupling the gun barrel liner to the gun chamber before applying the top coating. 17. The method of claim 16, further comprising threading an inner surface of the gun chamber complementary to the threaded outer surface of the gun barrel liner. 18. The method of claim 16, wherein fixedly coupling the gun barrel liner to the gun chamber comprises at least one of tack welding, soldering, or brazing the gun barrel liner and the gun chamber. 19. The method of claim 15, wherein cold gas-dynamic spraying the gun barrel liner comprises cold gas-dynamic spraying the gun barrel liner with the top coating until the top coating is between approximately 0.300 inches and 0.500 inches thick.
