  • Patent number: 6706993
    Abstract: The present invention provides a plasma transferred wire arc torch assembly that includes a monolithic block assembly that combines into a single component several features that have previously been separate components. The monolithic block of the present invention combines the functions of a wire guide, an air baffle, and a nozzle. Integration of this components allows for a reduction in size of the plasma transferred wire arc torch assembly thereby making it possible to coat smaller diameter bores with metal.

  • Patent number: 6686557
    Abstract: The present invention provides a nonflammable ternary gas mixture to be used in a plasma machining operation. The ternary gas mixture of the present invention comprises from about 4% to about 6.2% hydrogen, 30% to 50% argon, and the balance nitrogen. In another embodiment of the present invention, a method of generating a high pressure plasma is provided. The method of this embodiment comprises introducing the ternary gas mixture of the present invention into a plasma torch apparatus, initiating a plasma in the plasma torch apparatus, and sustaining the plasma with a high voltage between a cathode and an anode.
