Coating with Tungsten Carbide (WC) by PTA  or Laser Cladding technology for Spear Head and Nozzle of Hydro-turbine in hydroelectric power plants:

Working Condition of Spear Head and Nozzle of Hydro-turbine: Working under very high pressure, it is subject to high wear, corrosion, erosion and cavitation, so coating the surface layer with super hard, wear-resistant, corrosion-resistant materials is extremely necessary.

Characteristics of Tungsten Carbide: high hardness, extremely high wear resistance and corrosion resistance. Even in harsh working environments such as high temperatures, chemicals, etc., this material still shows its inertness.

Repair and recovery:

  • Coating by Laser Cladding/PTA technology with a layer thickness according to specifications and enough for machining, grinding to turn back to the required dimension.
  • Powder: Tungsten Carbide (WC).
  • Finish by polishing method, then measure to ensure the required specifications.

We specialize in providing welding, restoration, and hard coating services for mechanical parts that are resistant to abrasion, corrosion, high temperature…
