Spray & Fuse
Spray & Fuse is a thermal spraying process that is finished with a post-treatment in which the applied coating melts into a wear-resistant, dense, and tough layer.
This technique is often used for applications where coatings are subject to high wear, impact loads, or corrosion.
Spray & Fuse is a hot process, whereby the coating ultimately forms a metallurgical bond with the substrate.
How Does the Process Work?
- An alloy is first sprayed cold (as in flame spraying).
- The component is then heated locally (usually with a flame burner) to just above the melting point of the coating.
- The coating melts and flows together with the substrate.
- After cooling, a seamless, pore-free coating with excellent adhesion is formed.
Features
Very high wear resistance and toughness
Metallurgical bonding (stronger than conventional thermal coatings)
Dense, homogeneous, and resistant to erosion/corrosion
Requires experience and precise temperature control
Typical applications
- Conveyor rollers, scrapers, worm shafts
- Machine components subject to impact or abrasive loads
- Industrial knives or wear parts
- Components in the food industry or chemical industry, where porosity is undesirable
Capabilities at Plasmajet
- Ability to treat complex shapes locally
- Can also be used on larger parts (up to Ø 2000 mm and 10 m length via robot)
- Precision machining possible after the process: grinding, lapping, etc.
A wear-resistant coating that really sticks?
Spray & Fuse is the perfect blend of flexibility and robustness. Ideal for heavy-duty applications.
