| 106 | Apparatus and method for applying coatings onto the interior surfaces of components and related structures produced therefrom | US10584682 | 2005-01-10 | US20090017217A1 | 2009-01-15 | Derek D. Hass; Haydn N. G. Wadley |
| Provided is a methodology and system for applying coatings onto the interior surfaces of components. The approach comprises a vapor creation device (for example an electron beam or laser that evaporates a single or multiplicity of solid or liquid sources), a vacuum chamber having a moderate gas pressure (between about 10−4 to about 103 Torr) and a inert gas jet having controlled velocity and flow fields of gas jet. The gas jet is created by a rarefied, inert gas supersonic expansion through a nozzle. By controlling the carrier gas flow into a region upstream of the nozzle an upstream pressure is achieved (i.e. the gas pressure prior to its entrance into the processing chamber through the nozzle). The carrier gas flow and chamber pumping rate control the downstream (or chamber) pressure (i.e., downstream of the nozzle). The ratio of the upstream to downstream pressure along with the size and shape of the nozzle opening controls the speed of the gas entering the chamber. The carrier gas molecular weight (compared to that of the vapor) and the carrier gas speed controls its effectiveness in redirecting the vapor atoms via binary collisions towards the substrate. The speed and flux of the atoms entering the chamber, the nozzle parameters, and the operating chamber pressure can all vary leading to a wide range of accessible processing conditions. Vapor created from a source is transported into the interior regions of a component using binary collisions between the vapor and gas jet atoms. Under certain process conditions these collisions enable the vapor atoms to scatter onto the interior surfaces of the component and deposit. | ||||||
| 107 | Processing of rifled gun barrels from advanced materials | US11480639 | 2006-07-03 | US20080120889A1 | 2008-05-29 | Animesh Bose; Robert J. Dowding; Jeffrey J. Swab |
| Gun barrels made from advanced materials have the potential to provide a significant increase in barrel life as well as a reduction in weight (for advanced ceramic materials) for small caliber systems. The potential use of advanced materials as gun barrels is severely limited due to the difficulty in introducing the rifling pattern on the inner diameter. Most projectiles coming out of the guns are spin stabilized (for aerodynamic flight stability). This spin is imparted by a rifling pattern (lands and grooves) in the inner surface of the gun barrel. The processing of gun barrels made from advanced materials with internal rifling pattern poses a tremendous processing challenge to the materials community. The rifling lands and grooves and desired twist rate coupled with the difficulty of machining some of the advanced materials (ceramics, cermets, hardmetals, etc.) makes the economic manufacturing of such gun barrels extremely difficult. Currently, this form of rifling is achieved by machining in case of metallic gun barrels.The limitation in producing the rifled pattern lies with the conventional processing of complex shaped advanced materials such as ceramics, cermets, or hardmetals. Shaping of these typically requires careful diamond grinding. This grinding process is not only very expensive but it also introduces flaws in case of the brittle ceramics (microcracks). These flaws are detrimental to the performance of these advanced materials as rifled gun barrels. Thus, there is an opportunity and challenge to the materials community to come up with a processing solution that will allow advanced materials such as silicon nitride (Si3N4), SiAlON, hardmetals, etc. to be used as gun barrels that have the rifled pattern in the inner diameter.Herein are provided methods and compositions useful to form the rifled gun barrel tubes from advanced materials using little or no machining of the internal rifled geometry. | ||||||

| 115 | Wear resistant gun barrel and method of making the same | US3780465D | 1972-06-01 | US3780465A | 1973-12-25 | POLCHA R |
| A wear resistant gun barrel and method of producing it is disclosed. The barrel has hardened zones or lands which penetrate into the barrel material between rifling grooves and which are highly resistant to wear from repeated projectile firings. The hardened zones or lands are produced by heating a narrow zone on the outside of the gun barrel with a high intensity heat source, allowing any desired pattern to be melted into the steel. The molten zones, when cool, produce areas having increased hardness. The final step is to machine the gun barrel to the proper inner diameter and engrave rifling grooves between the hardened zones. In the case of large caliber gun barrels the hardened zones are provided in an inner liner which is then shrunk fit into the outer cylinder before the machining step is performed.
