Torispherical tungsten carbide powder has high hardness, density and melting point. It is an important industrial raw material, which is widely used in surface strengthening, abrasive, cutting tool and other industries.
Characteristic
The shape of the torispherical tungsten carbide powder is a standard sphere, and the surface of the powder particles is smooth and dense. The powder hall liquidity has been greatly improved, and the hardness, density, and melting point are extremely high. These make it more difficult to produce and process.
Preparation
Plasma technology is an ideal method for preparing torispherical tungsten carbide powder, and it can control the particle size of the powder more precisely. The plasma method has a certain ability of purifying the powder material in the preparation process. Utilizing the high temperature of the plasma as a heat source, the tungsten powder is melted and vaporized, thereby realizing the spheroidization process of the irregular raw material powder.
