Flame Spray

Flame Spray Coating Info & Benefits

Flame spray coating is a process in which melted (or heated) materials are sprayed onto a surface. The “feedstock” (coating precursor) is heated by electrical (plasma or arc) or chemical means (combustion flame).

  • During the coating process, there is no Distortion of the part being coated. The part temperature generally is below 250° F (121° C) during the spray operation. The substrate of the part that is coated does not metallurgically get altered.
  • Virtually any material can be applied to any metal substrate, and some plastics; including ceramics, carbides, pure metals, alloy metals, and much more.
  • Coating buildup can exceed .100 (2.54mm) in thickness, with some materials able to be applied over .200 (5.08mm) thick.
  • The application time is very fast, unlike plating applications that take hours to accomplish a minimal buildup. This can reduce downtime during repairs.
  • Flame sprayed coatings will increase component life, helping to extend the life cycle of equipment, therefore reducing maintenance costs. When necessary, the coating can be removed with virtually no degradation to the part base material, and reapplied to restore and place the component back in service.
  • Finished parts are protected by masking, so that only the surface requiring coating buildup gets coated, with the rest of the part remaining free of any coating attachment.
