Spray & Fuse Hardfacing

Spray & Fuse Hardfacing In this process, a combustion powder spray gun is utilized to deposit a wide variety of materials onto a substrate.

In this process, a combustion powder spray gun is utilized to deposit a wide variety of materials onto a substrate. The powders used for spray and fuse hardfacing are typically compositions of Ni, Cr, Co, Bo, Fe, W and WC in varying blends. After the coating has been sprayed to a pre-determined thickness, an oxygen-acetylene torch, or a furnace, is used to heat the part to approximately 2000 degrees Fahrenheit, fusing the coating within itself and to the substrate, thereby achieving a true metallurgical bond. With this process, coatings can be applied with a hardness up to 80Rc.

Spray & Fuse Hardfacing Coating Process

In the first stage of spray and fuse hardfacing process, the combustion powder application of material is performed. Then, the coating is pre-heated. After this stage, the coating is locally heated until cherry red at which point the material has been fused onto the substrate. The process reaches completion when the opposite end of the part reaches the fused state.

Advantages of Spray & Fuse Hardfacing

  • Extremely hard
  • Metallurgical bond of coating to substrate
  • Resistant to impact and chipping
  • Corrosion resistant
  • Enables easy surfacing of edges
  • Minimized distortion and oxidization
