Spray tungsten powder is the crystal tungsten powder after spraying, which is applied to surface spraying, with high purity, high surface hardness, good grit, good toughness, low oxygen content, wear resistance, corrosion resistance and so on.
Application
Spray tungsten powder is mainly used in surface coating, oil perforating, hard facing materials, high temperature resistant coatings, high temperature combustion chamber spraying coating and other wear-resistant coating, high temperature resistant parts, intermediate frequency furnace tungsten crucible coating.
Preparation
According to the special performance requirements of spray powder, the use of blue tungsten oxide as raw materials, adding alkali, the mixing, in molybdenum wire furnace for hydrogen reduction, will be the crystal ball mill tungsten powder, and the quantitative solvent washing, finally, drying, sieving, batch, the request to packaging to be detected.
