THERMAL METAL SPRAY POWDERS (PTA/LASER/SPRAY & FUSE)

WEAR PROTECTION WITH THERMAL SPRAY POWDERS

Wear protection with Thermal Metal spray Powders is versatile method of depositing high quality deposits on relatively low cost surfaces. Medium and high hardness materials, and carbide composites can be deposited on a variety of metals to achieve diverse properties such as mechanical strength, wear and corrosion resistance. More then 150 different metal powders are available to suit most applications

We supply Metal Powders for use with the following Processes:

  • Cold spraying (CS)
  • Detonation flame spraying
  • Oxy-acetylene powder welding , Spray & fuse (S&F)
  • Plasma spray (APS ) & Plasma transferred arc surfacing (PTA)
  • High velocity oxy-fuel spraying (HVOF-HVAF )

EQUIPMENT SUPPLIED FOR POWDER FLAME SPRAYING /WELDING

  • A simple to use and cost effective spray & fuse torch to protect and repair valuable components against wear and tear.
  • Metal powders are applied with this special oxy acetylene torch and fused simultaneously to the surface of the metal part.
  • Precise and thin overlays can be made by diffusion ensuring a perfect bond below the melting point of the base metal.
  • Coatings made by this process have only a minimum of dilution and therefore retain the original properties.
  • No special training of operator required.

Set/ Kit as shown includes the following :

  • Torch with powder hopper
  • 5 different spraying nozzles (1-5)
  • 2 large heating/spraying nozzles
  • 2 quick couplings
  • Set of O rings and wrench
  • Carry box
