Tungsten Carbide Coating

  • High Velocity Oxygen Fuel Spraying Tungsten Carbide Powder Coating

    High Velocity Oxygen Fuel Spraying Tungsten Carbide Powder Coating

    High Velocity Oxygen Fuel Spraying Coating

    Technical Advantages:

    1,Three working mode:economic,Superior,Ultra

    More uniform coating structure and high density(porosity less than0.2%)

    Less or none decarb (undetectable by XRD)

    Higher coating hardness(greater than 1600 HV0.3),less variations thru the coating areas(50-60HV vs.150-200 HV for conventional HVOF)

    More wear resistant

    Higher toughness and cavitation resistant properties

    Gas tight with 50um thick WC coating under 200MPa nitrogen gas

    Higher spray rate:5-10um/pass

    Coating defect can be repaired locally.
