Coatings & Uses

Dual Wire Arc Spray

The dual wire arc process melts two wires simultaneously and propels the atomized particles to the substrate using compressed air. With this process, we do use a nickel bond wire to provide a higher bond strength. The wire arc is a low-cost process for wear, size restoration, and many more applications. Unlike the other flame spray processes, the wire arc can provide coatings up to 1/4” thick. The most common alloys we use are Stainless Steel, Carbon Steel, Copper, Aluminum Bronze, Nickel Chrome, Babitt, Cored wire carbides.

Typical Applications:

  • Pump Housings
  • Size restoration
  • Shaft, Bearing, & Sleeve Rebuild
  • Printing RollsWear Plates

High Velocity Oxy Fuel Spray (HVOF)

HVOF systems operate at supersonic gas velocities greater than mach 5 before impact into the substrate. This results in a high quality, very dense, low porosity coating. HVOF tungsten carbide coatings are used in areas of extreme wear and have excellent corrosion resistance. We use this coating as a direct chrome replacement as it usually wears 3-5 longer than chrome plating.

Typical Applications:

  • Progressive cavity pump rotors
  • Impellers
  • Wear Plates
  • Fan Blades
  • Chrome Replacement

Plasma sprayed Ceramics

Plasma Spraying makes use of the plasma torch for heating and spraying the coating. The powder is melted down, and is then sprayed on the part in a similar fashion as combustion flame spraying. Plasma applied ceramics have the advantage of spraying materials that have a much higher melting point, are denser, and have a much higher bond strength compared to other spray methods. Plasma coating are used commonly for applications in aerospace, automotive, agricultural, and medical fields. We have plasma applied ceramics that offer corrosion resistance, thermal protection, electrical insulation, and abrasion resistance.

Typical Applications:

  • Shafts (seal areas)
  • Impellers
  • Wear plates
  • Corrosion Resistance
  • Wear Resistance
