Description
Spray and fuse is a continuous brazing process that applies the coating and fuses it to the base material in a single process. This process does not melt the base material and consequently there is no dilution of the overlay alloy. The bond is created by the diffusion of atoms between the overlay alloy and base material resulting in a very dense, hard coating with high bond strength.
Features & Benefits
- Allows the use of harder WC/WC2 carbides which provide better wear resistance than mono crystalline WC carbides
- Provides better wear life in high impact conditions
- More even carbide distribution extends service life
- No formation of brittle intermetallic phases greatly reduces cracking
- Economical application of thick overlays
- Capable of applying thick overlays, up to 1” (25mm) for maximum service life
- Spray and fuse overlays are excellent in high impact applications such as Tee spools
- Overlays can be applied to registered pressure equipment and piping
