  • Publication number: 20130011569
    Abstract: A method for arc spraying in which at least one wire-shaped spray filler material is melted in an arc by means of electric current and atomised by means of an atomising gas flow and applied in the form of a particle stream onto a workpiece, at least one wire-shaped spray filler material being preheated before the melting in the arc.
    Type: Application

  • Publication number: 20070045248
    Abstract: An apparatus for producing a vacuum arc plasma source device using a low mass, compact inductive energy storage circuit powered by a low voltage DC supply acts as a vacuum arc plasma thruster. An inductor is charged through a switch, subsequently the switch is opened and a voltage spike of Ldi/dt is produced initiating plasma across a resistive path separating anode and cathode. The plasma is subsequently maintained by energy stored in the inductor. Plasma is produced from cathode material, which allows for any electrically conductive material to be used. A planar structure, a tubular structure, and a coaxial structure allow for consumption of cathode material feed and thereby long lifetime of the thruster for long durations of time.
