Spherical Tungsten Carbide Powder Introduction
Apr 24, 2018

Tungsten carbide can be obtained by high temperature heating of a mixture of tungsten and carbon. The presence of hydrogen or hydrocarbons can accelerate the reaction. Tungsten carbide powder is an important thermal spray material. Currently used thermal sprayed tungsten carbide powder is usually produced by casting methods. The powder has a polygonal shape, poor fluidity and low hardness, and it is difficult to meet the requirements of high performance thermal spray materials.

Compared with ordinary tungsten carbide powder, spherical tungsten carbide powder has two prominent features: First, the appearance of spherical powder, powder mobility, surface quality after coating the workpiece is high; Second, the powder internal fine grain, hardness Larger, more wear-resistant coating, spherical tungsten carbide powder as a high-temperature thermal spraying material, due to its unique preparation technology and excellent performance, has attracted close attention of domestic and foreign markets and researchers, invest a lot The human and material resources for research and development.
