Spherical tungsten carbide powder has the uniqueness of the preparation technology and excellent performance, is a high-tech materials, thermal spraying spherical appearance, internal grain fine powder, high hardness and better the wear resistance of the coating, powder, good fluidity, etc.
Characteristic
Compared with the common polygonal tungsten carbide powder, the spherical tungsten carbide powder has two remarkable characteristics: first, the appearance is spherical, the powder fluidity is good, and the surface quality of the workpiece is high. The second is the fine grain size, hardness and wear resistance of the coating.
Preparation
Spherical tungsten carbide powder is heated by a mixture of tungsten and carbon, and the presence of hydrogen or hydrocarbons accelerates the reaction.
