Estimating the term…
A metal jet cutting system, which includes a jetting heat, a heater and a power source, is used for modifying a workpiece. The jetting head includes a crucible and an inlet for receiving a feed stock of a conductive material. The heater melts the conductive material in the crucible to provide a conductive fluid, which exits the jetting head via an outlet. The power source, which is in electrical communication with the conductive fluid, increases the temperature of the conductive fluid. The conductive fluid is applied to the workpiece to modify the workpiece.
A conductive fluid jet cutting system for modifying a workpiece comprising:
A conductive fluid jet cutting system comprising:
A crucible for a conductive fluid jet cutting system, wherein the crucible comprises side walls and a base, a portion of the crucible being formed of a zirconium containing compound that is electrically conductive and is resistant to dissolving in the presence of a metallic melt, the crucible being configured to allow a current from a power supply to flow from the portion of the crucible to a conductive fluid being dispensed from the crucible.
A nozzle for a conductive fluid jet cutting system, wherein the nozzle comprises a disk-structure having an orifice, wherein the orifice is located at a center of the disk-structure, a portion of the nozzle being formed of a zirconium containing compound that is electrically conductive and is resistant to dissolving in the presence of a metallic melt, the nozzle being configured to allow a current from a power supply to flow through the nozzle to a conductive fluid jet being dispensed through the nozzle.
