    摘要： An integrated barrel assembly, configured to cooperate with a firearm receiver assembly firearm, comprises a barrel having a breech end and a muzzle end and a connector for securing and aligning it with the receiver assembly. The design eliminates the need for a separate barrel and barrel extension and improves the structural integrity and performance of the firearm. The barrel defines a bolt head cavity, a chamber, and a bore all in fluid communication and serially extending from its breech end to muzzle end, and an internal breech face is created where the bolt head cavity meets the chamber. The bolt head cavity comprises bolt-locking lugs and angled feed ramps, and the chamber and bore are configured to cooperate with a particular cartridge case and projectile. The barrel preferably comprises steel or a steel alloy and a coating applied to the barrel's outer surface, inner surface, ends, and gas port.

    摘要： 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.

    摘要： A method of coating an inner surface of a weapon barrel includes the following steps: directing a laser beam against the inner barrel surface to cause melting of regions thereof; introducing a coating material in one of powder, wire and ribbon form into the laser beam for melting the coating material to produce in the surface regions a molten bath composed of the molten coating material and a material of the weapon barrel; and moving the laser beam inside the weapon barrel axially thereof and relative thereto, whereby the molten substance of the bath becomes rigid as the laser beam moves away therefrom.

    摘要： A method of providing an inner surface of a weapon barrel with a hard chromium layer includes the steps of forming the hard chromium layer on the inner surface by galvanic separation; and thereafter heating the hard chromium layer beyond the re-crystallization temperature thereof for obtaining, upon conclusion of the heating step, a uniform re-crystallization of the hard chromium layer in its entirety.
