Combustion Powder  Spray

We continually feed the spray material in powder form into a fuel gas-oxygen flame where it is typically melted by the heat of combustion. A powder feed carrier gas transports the powder particles into the combustion flame. The mixed gasses entrain the melted particles onto the prepared workpiece surface where it rapidly solidifies to form the coating.

Key characteristics

• Excellent for basic wear, corrosion resistance and abradable/clearance control applications
• Coatings can be machined to final dimensions and finish

Typical applications

• Crank shafts
• Sucker rod couplings
