Torispherical cast tungsten carbide powder has the advantages of good fluidity, good wear resistance and excellent overall performance. The structure is uniform and dense, which is conducive to surfacing and thermal spraying, so that the coating material has excellent performance.
Characteristic
Torispherical cast tungsten carbide powder is chemically more stable and has higher hardness than ordinary polygonal tungsten carbide powder. Its microstructure is slender equiaxial branches, without hypereutectic and hypoeutectic. When used, there is no stress concentration and microcrack, no sharp edges, and higher toughness and wear resistance than crushing powder.
Applications
Torispherical cast tungsten carbide powder has a uniform and dense structure, which is conducive to surfacing and thermal spraying, so that the coating material has high wear resistance, high toughness, and excellent performance.
Preparation
Tungsten powder, carbon black, tungsten carbide precursor or polycrystalline tungsten carbide as raw materials, it can produce torispherical cast tungsten carbide powder with good fluidity, good wear resistance and excellent comprehensive performance by high-temperature melting, inert gas ultra-high temperature atomization,
