    摘要: Die Erfindung betrifft ein Verfahren zur Innenbeschichtung eines Waffenrohres, auf dessen innere Oberfläche (13) mindestens in einem Teilbereich (2) mindestens eine Schicht (21) eines Schichtwerkstoff zur Vermeidung von Erosionen aufgebracht wird. Um auf einfache Weise hochschmelzende Schichtwerkstoffe auf die innere Oberfläche (13) des Waffenrohres (1) aufzubringen, schlägt die Erfindung vor, die Innenbeschichtung des jeweiligen Waffenrohres (1) durch Laser-Auftragsschweißen vorzunehmen, wobei auf die innere Oberfläche des Waffenrohres ein entsprechender Laserstrahl (12) gelenkt wird, der die oberflächennahen Bereiche (100) des Waffenrohres (1) aufschmelzt. Der Schichtwerkstoff wird in pulver-, draht- oder bandförmiger Form kurz vor dem Auftreffen des Laserstrahles (12) auf die innere Oberfläche (13) des Waffenrohres (1) eingebracht und durch diesen geschmolzen, so daß sich im oberflächennahen Bereich (100) des Waffenrohres (1) ein den geschmolzenen Waffenrohrwerkstoff und den Schichtwerkstoff enthaltendes Schmelzbad (14) ausbildet, welches bei der Weiterbewegung des Laserstrahles (12) erstarrt.

    摘要: The invention provides an improved shotgun barrel (10) which includes a plurality of lands (14), for example, six, which reduce spin or rotation of the wad and hence reduce the dispersion or spread of the associated shotgun pellets. The lands are formed by depositing a material, for example, chrome, onto the barrel's internal surface (12). The lands (14) extend for the full length of the barrel and are preferably equidistantly spaced around the barrel and parallel to the barrel's central axis.

    摘要: 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 (22) is of a refractory material which may be a metal refractory or a non-metal refractory. The liner (28) is bonded to an outer jacket material formed of an alloy of nickel, aluminum and molybdenum. The coefficient of expansion of the liner (28) 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 composite projectile barrel is disclosed comprising a continuous fiber composite outer shell whose average effective coefficient of thermal expansion in the longitudinal direction approximately matches that of an inner liner. In one embodiment, the composite barrel comprises PAN precursor carbon fiber and a thermoset epoxy resin, with the carbon fiber wound at varying winding angles to form a plurality of regions within the outer shell. The finished barrel exhibits light weight, superior axial stiffness and strength, durability, and is reliably accurate.

    摘要: A chamber reinforcement for composite firearm barrel and method for forming the same. In one embodiment, the barrel includes an inner tube defining a bore that provides a bullet path and an outer sleeve preferably made of a material lighter in weight than the tube. In some embodiments, the inner tube is made of a material that preferably has a greater density and strength than the outer sleeve. The reinforcement in one embodiment may be in the form of an end cap disposed on a portion of the sleeve. The reinforcement preferably is made of a material comparable to the inner tube in density and strength to reinforce the area where a chamber is formed for receiving a cartridge. In the preferred fabrication, the reinforcement, tube, and sleeve are forged together to provide a strong and unitary structure for withstanding combustion pressures and forces associated with discharging the firearm.

    摘要: An electrical energy-insulating, preferably ceramic, insert (15) which is fitted in a barrel (2) is adapted in order to prevent electrical energy transmission (16) from an electric igniter (3) to a barrel body on firing of an ammunition unit (11) which can be initiated with the electric igniter (3) . The insert is arranged in a position for firing of the ammunition unit. By means of the invention, a simple solution is obtained to the problem of electrical energy transmission by virtue of the fact that other measures do not have to be taken, for example the cases of the ammunition units do not have to be adapted by complicated and cost-increasing measures.
