Spray spherical tungsten powder is widely used in the field of thermal spraying, which not only has good fluidity, but also has a more uniform and compact coating, so the product has better wear resistance.
Plasma melting spheroidizing technology is considered to be one of the most effective means to obtain compact and regular spherical tungsten powder. Radio frequency induction plasma has high energy density, high heating intensity and large plasma torch. Since it has no electrodes, it will not pollute the product due to evaporation of the electrode.
Radio frequency (RF) plasma in the process of powder of spheroidizing, its high temperature to provide enough energy to make powder through plasma absorption of heat, melt quickly, and under the effect of surface tension of condensed into spherical, the quench solidification in a very short period of time, thus forming spherical powder.
