Nano spherical tungsten carbide powder has spherical particles, good quality, clean, less pollution, small size and narrow size distribution range. It is an important thermal spraying high-tech material and can be prepared by plasma method.
Application
As a new high-tech material for thermal spraying, nano spherical tungsten carbide powder can meet the requirements of high-performance thermal spraying materials due to its good fluidity and high hardness.
Preparation
Plasma technology is considered to be the most effective method for obtaining nano spherical tungsten carbide powder. The basic principle of the plasma method is form ultrafine particles in an inert or reactive atmosphere by direct current discharge (or other means) in an inert atmosphere or a reactive atmosphere to generate a high temperature plasma, thereby melting and evaporating the metal, obtaining metal vapor, quenching, or chemical reaction.
