摘要： A plasma arc torch that includes a torch body having a nozzle mounted relative to a composite electrode in the body to define a plasma chamber. The torch body includes a plasma flow path for directing a plasma gas to the plasma chamber in which a plasma arc is formed. The nozzle includes a hollow, body portion and a substantially solid, head portion defining an exit orifice. The composite electrode can be made of a metallic material (e.g., silver) with high thermal conductivity in the forward portion electrode body adjacent the emitting surface, and the aft portion of the electrode body is made of a second low cost, metallic material with good thermal and electrical conductivity. This composite electrode configuration produces an electrode with reduced electrode wear or pitting comparable to a silver electrode, for a price comparable to that of a copper electrode.

摘要： An electrode for a plasma arc cutting torch which minimizes the deposition of high emissivity material on the nozzle, reduces electrode wear, and improves cut quality. The electrode has a body having a first end, a second end in a spaced relationship relative to the first end, and an outer surface extending from the first end to the second end. The body has an end face disposed at the second end. The electrode also includes at least one passage extending from a first opening in the body to a second opening in the end face.

摘要： A method and apparatus for forming mono-sized-dispersed spherical particles from a conductive liquid utilizes inductive coupling to cause a pressure oscillation in a plenum feeding a jet-forming nozzle. The inductive coupling is provided by a transformer where one loop is the conductive liquid. The invention also features a device with single or multiple orifice nozzle plates reliably manufactured using etching techniques. The invention also features methods for protecting jet-forming orifices from destruction attack by a corrosive liquid. The invention also features means to create simultaneously, tailored mixtures of mono-size-dispersed powder sizes. The invention also features a system and method for “pre-wetting” fine pores and orifices and for encouraging liquid penetration of the fine pores and filter without recourse to very high differential pressure.
