Flame spraying
Flame spraying is one of the oldest and most accessible thermal spraying techniques.
An autogenous flame is used to melt a wire or powder, which is then applied to a surface at high speed.
This method is ideal for applying metallic coatings for corrosion protection, wear resistance, and surface repair.
The process is simple, robust, and versatile.
How Does the Process Work?
- A metal wire or powder is continuously fed into an acetylene/oxygen flame (~2900°C).
- The molten material is accelerated by compressed air and projected onto the surface.
- The coating adheres mechanically to the substrate.
Advantages
Cold technique: little thermal impact on the workpiece
Budget-friendly solution
Quick application, even on site
Mechanical adhesion (i.e., required roughness of the substrate)
Capabilities at Plasmajet
- Parts up to 2500 mm in diameter and 10,000 mm in length
- Can also be used for parts with limited access or complex geometry
- Mobile application possible (on-site repair)
Typical applications
- Anti-corrosion coatings on steel structures
- Repair of shafts, bearing seats, or mating surfaces
- Application of sliding layers (e.g., with molybdenum)
- Pre-treatments or undercoats for other coatings
