Spray Drying of Tungsten Copper Alloy

The spray drying process of tungsten copper consists of three stages: spray drying, preparation and hybrid of original liquor and conversion of fluidized bed.

This method is used to prepare WC-Co, W-Ni-Fe and various tungsten copper alloy and nano composite powder. The comprehensive mechanical properties of tungsten copper prepared by the method are obviously improved, and the service life is three times higher than that of conventional products, the process is easy to operate, no impurities and has broad prospects.

The powder obtained by this process can be converted into metal composite powder by fluidized bed, mixing a variety of metal salt solution, quickly injected into the drying chamber through the nozzle to obtain metal salt particles, roasting it, ultrafine particles of nano crystalline oxide composite powder precursors were obtained. Under certain conditions, the precursor powder is obtained through reduction or carbonization to obtain alloy composite powder or carbide.
