Abstract:
1. A direct current plasma apparatus comprising: a housing; a cathode disposed in said housing; an annular channel generally disposed adjacent said cathode, said annular channel configured to fluidly transmit a plasma gas; an anode positioned operably adjacent to said cathode to permit electrical communication therebetween sufficient to ignite a plasma jet within the plasma gas; a precursor source containing a precursor material; a precursor outlet line extending through at least a portion of said cathode, said precursor outlet line terminating at at least one opening, said at least one opening being offset from a tip of said cathode to generally prevent deposition of said precursor material at said tip of said cathode, wherein said plasma jet is capable of entraining, melting, and depositing at least some of said precursor materials upon a target.
