Thermal spraying powders Tungsten carbide cobalt WC-CO

    In recent years, the research of the tungsten carbide cobalt nanoparticles thermal spraying with nanostructure coatings become the new trend. as a wear resistant coating, due to its good the hardness and toughness, it is widely used in aerospace, metallurgy, machinery fields. Relative to the hard chromium plating, thermal spraying tungsten carbide cobalt ceramic coating have obvious advantages on abrasion resistance, corrosion resistance, fatigue resistance, what's more, it have fast preparation speed, low cost, good environment. in some application areas, such as aircraft landing gear, the thermal spraying WC2CoCr coating is replacing hard chrome plating.

    Nano tungsten carbide cobalt thermal spraying powders preparation from Hongwu nanometer:

1. the precursor solution preparation with soluble salt containing tungsten, cobalt mixing chemical composition.mix them evenly, spray drying, roasting, reduction and carbonization.getting Nanocrystalline WC-Co composite powders;

2. nano tungsten carbide cobalt WC-Co composite powders composition can be adjusted according to the using needs,such as adding some other alloying elements growth inhibitor, and the elements content can be accurately controlled.

3. nano tungsten carbide cobalt WC-Co composite powders, grain size of WC phase is 60nm with low content of impurities.

4. product technology processes mature sound, own a full set of equipment, low cost, large output, high cost performance.
