Plasma Rotating Electrode Process Equipment (PREP)
Plasma Rotating Electrode Process are developed to produce nickel based alloy powders, titanium alloy powders, stainless steel alloy powders and other refractory metal powder. The high quality metal powders produced by PREP are widely used for Electron Selective Melting, Laser Melting Cladding, Coating and Hot Isostatic Pressing etc.
Firstly, make the metal or alloy into the self-consuming electrode bars. a plasma arc is used to melt the end of a rapidly rotating bar and molten droplets are spun off and solidify in flight in an insert atmosphere.
Ø The PREP powders are high quality with very clean and smooth surface, very low internal porosity and satellites, less gas inclusion.
Ø Process parameters are set simply, easy to operate and automatic production;
Ø A wide range of application and can be used for production of Ti, Ni, Co and other refractory alloys
