Thermal spraying involves heating materials in either a powder or wire form to a molten or semi-molten state and propelling it using a stream of gas or compressed air, depositing a layer on the surface of the main component. This process can be repeated many times, allowing the technician to build up a series of layers. At APR, we use Twin Wire Arc Thermal Spray equipment. This equipment involves two wires that are electrically charged in the gun to induce melting. The molten material is then propelled onto the component. Not only does this equipment allow for a thicker build-up for excellent dimensional repair, but it also provides highly reliable, controlled surface results.

Benefits of Thermal Spraying:

  • Resist Wear and Fretting
  • Slow Down Corrosion
  • Control Clearances
  • Salvage Worn Components
  • No need to buy a new component from the OEM

Thermal spray coatings can be the most cost-effective means of protecting substrate surface from wear and corrosion. Other primary uses of thermally sprayed coatings include dimensional restoration and maintaining precise clearances.

Common Applications:

  • Repair and Reconditioning
  • Anti-Corrosion
  • Heat Shield
  • Cavitation, Wear and Erosion Prevention
  • Insulation
  • Shaft Repair
  • Bearing Fit Rebuild
