Spray and Fuse Coating with LINDOFLAMM Burners
Strengthening the Bond Between a Coating and Its Substrate
Our LINDOFLAMM® burners are designed to accelerate the fusion of flame-sprayed coatings, enabling you to achieve harder, denser, more homogenous results with greater precision
Fusion of Flame-sprayed Coatings: Advantages
Flame spraying is widely used for building up worn shafts and component faces and for coating steel with a corrosion-resistant zinc layer. It is also used for hard facing.
The fusion of flame-sprayed coatings involves heating the coating to its melting point to strengthen the bond between the coating and the substrate. A flame is usually applied to heat the coating. Fusing takes place at temperatures between 950°C and 1250°C (1742°F and 2282°F), producing a wet shine on the surface. After flame spraying, coating fusion helps to eliminate porosity in the deposition and to obtain dense, homogenous and strong coatings with good resistance properties.

Not only do our burners deliver harder, denser coatings, they also accelerate process times and enhance precision. In addition, they can be fully automated.
LINDOFLAMM for Fusing: Benefits at a Glance
- Fine-tuning of flame-sprayed coatings
- Improved hardness and density of coatings
- Rapid annealing of coatings with acetylene as fuel gas
- Reduced oxides on the machined surface / substrate
- Burner selection adapted to your demands
- Water-cooled and automated burner equipment available
- Customized gas supply solutions
The Right Fuel Gas for Fusing of Flame-sprayed Coatings
The preferred fuel gas for fusing processes is usually a high-performing one like acetylene. The high-temperature acetylene flame will melt only the coating material, thus bonding the coating particles to each other while removing oxides from the deposition material. Our LINDOFLAMM special burners operate with an oxy-acetylene mix.
