the MIM metal injection molding of cemented carbide powder

In metal injection molding MIM, another important powder is cemented carbide powder, it is a mixture of tungsten carbide and cobalt powder powder, cobalt powder and tungsten carbide inspection milling time can reduce the average particle size of powder particles, and on the surface of tungsten carbide wrapped a layer of cobalt in the process of sintering, cobalt powder melt into liquid phase, when cooling solidification as a kind of hard phase, after grinding powder its standard oxygen content of 0.07%, all other refractory metal chromium, molybdenum content of about 0.01% in general.
