Performance and application characteristics of nickel-coated tungsten carbide composite powder

       Nickel-coated tungsten carbide composite powder is a composite powder made of hard carbide as the core and nickel as the cladding layer. The core powders used are tungsten carbide, duplex tungsten carbide (TiWC2) and diamond. Diamond has the highest hardness, followed by duplex tungsten carbide, both of which are high-hardness materials.



     Nickel-coated tungsten carbide composite powder is most suitable for the preparation of high wear and corrosion resistant coatings, which are very dense and have low porosity.

     Nickel-coated tungsten carbide composite powder can be used to prepare high-quality wear-resistant and corrosion-resistant coatings by explosive spraying, supersonic flame spraying, protective gas plasma spraying, vacuum plasma spraying and other processes. Gas-stabilized plasma spraying can also be used.

     Nickel-coated tungsten carbide composite powder is used for coatings with resistance to low-stress abrasive wear, erosion wear, fretting wear and hard surface wear above 500 °C, such as mud pump plungers, sand blasting machine parts, sand mixer blades, water turbine blades , Deep water pump impeller and shaft, flue fan blade, screw mixer screw, wire capstan, etc.

     Nickel-coated diamond is especially suitable for cutting blades for high hardness materials.
