Abstract

Flow characteristics and temperature distribution in metal beads subjected to transferred arc plasma impingement is described based on combined mathematical models of the arc plasma and the metal target. This problem is of interest to ultrafine powders (UFP) generation by the "reactive arc plasma" process. The influence of operating parameters in this particular UFP production method on the heat and fluid flow in the metal are likewise examined. The flow behavior in the melt is characterized by a recirculating flow governed by electromagnetic forces. The size of the molten portion in the metal target is affected by the process gas and supplied current. The coolant temperature and gas inflow rate indicated no significant effect on the melt size.
