  • Patent number: 8203095
    Abstract: A method of material treatment in which the surface of a metal substrate is converted to a composite structure of the metal and its nitride or carbide utilizing a high temperature chemically active thermal plasma stream, and the product obtained from that method. The complex thermal plasma contains controllable additions of active gas, liquid or solid substances. The surface layer obtained is functionally graded to the substrate resulting in an excellent bond that resists delamination and spalling, and provides a significant increase in hardness, wear and erosion resistance, and corrosion resistance, and a decrease in coefficient of friction.

  • Patent number: 7955706
    Abstract: A cermet armor material for highly effective ballistic performance which is comprised of a layer of base metal in which is deposited a layer or layers of ceramic and a compatible metal such that the deposited metal in combination with the base metal forms a continuous matrix around the ceramic particles. The body has a structure which is continuously graded from a highest ceramic content at the outer surface (strike face) decreasing to zero within the base substrate, and contained no abrupt interfaces.

  • Patent number: 7721478
    Abstract: A fabrication technique is described for producing lighter weight and improved wear and erosion resistant gun barrels. The barrels are produced in an unconventional manner from the inside bore to the outside diameter of the barrel and combine a refractory metal, metal alloy, or ceramic composite inner liner with a metal matrix composite (MMC) or titanium or other suitable high strength, lightweight metal or metal alloy outer shell. A unique aspect of the invention is that there is a compositional gradation from the liner at the inside bore to the overwrap which extends to the outside diameter of the barrel. A process is also described to produce barrels with a refractory metal liner with improved wear and erosion resistance by depositing the refractory metal on the ID of a pre-fabricated barrel.
