Linearly-Graded Ceramic Coating Fabrication Process for Gun Barrels

Alameda Applied Sciences Corporation will use its proprietary Coaxial Energetic Deposition process to deposit a linearly-graded ceramic coating on the inside of gun barrels. This coating will transition smoothly from a fully ceramic interior surface, whichis exposed to the harsh firing environment, to a fully metallic base, which is directly interfaced with the metal barrel. Analytical tests will be performed to determine the properties of the coatings. It is anticipated that this coating will extend thelife of gun barrels, in particular, the barrels of future advanced guns, which are expected to use high-temperature propellants and fire at high rates. In addition to this application area, tests have shown that ceramic coatings deposited using our CoaxialEnergetic Deposition process extend the life of olefin production tubes. Alameda Applied Sciences is in negotiations to license this technology for olefin manufacturing.
