Flame Spray Coating System
Flame Spray System is the basic and cheapest process of thermal spray processes. This system shall spray both powder and wire acoording to the coating material alloy. Advantages of this system is less investment cost, high stuff ratio and less maintanance cost. But has less bond strength, high porosity and less flame temperature.
Principal of Flame Spray System:
Wire Flame Spray System sprays wire formed material with melting point less than oxy/acetylene gas mixture flame temperature. Coating wire is being fed in front of the gun by wire feed rollers. Wire is being melted in front of the gun by oxy/acetylene gas mixture flame. Melted wire is pulverised to the coated workpiece by high pressure air. Coated workpiece surface temperature is being between 95-200°C
