Abstract
A method of forming a gun barrel is disclosed that includes cold gas-dynamic spraying one or more coatings onto a mandrel. 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. The method may also include removing the mandrel.
Claims19
A method of manufacturing a gun barrel comprising:
- cold gas-dynamic spraying a mandrel comprising rifling with a first coating comprising at least one of tungsten carbide, chrome carbide, ceramic, and any combination thereof;
- and
- cold gas-dynamic spraying the mandrel with a second coating after cold gas-dynamic spraying the first coating, the second coating comprising at least one of a nickel based alloy or, a nickel-chromium based alloy or superalloy, and a cobalt based alloy or superalloy.
A method of manufacturing a gun barrel comprising:
- cold gas-dynamic spraying a mandrel comprising rifling with a first coating comprising at least one of an alloy, a superalloy, and any combination thereof.
A method of manufacturing a gun barrel comprising:
- cold gas-dynamic spraying a mandrel with an initial coating comprising at least one of tungsten carbide, chrome carbide, ceramic, and any combination thereof;
- and
- cold gas-dynamic spraying the mandrel with a second 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, copper powder, copper alloy powder, iron powder, iron alloy powder, nickel powder, nickel alloy powder, and any combination thereof.
