Powder flame spraying uses a powdery material with an acetelyn-oxygen flame which combustible gas expands and hung at the specimen surface and fuse. The bonding of the coat at the specimen will be vastly increased because of the thermal process. The coat will be gas- and liquid leak-proof.

Powder flame spraying:
1. Acetelyn / Oxygen
2. Powder container
3. Bruner nozzle
4. Support gas + Powder
5. Acetelyn / Oxygen – Flame and spray particle
