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.
