Thermal spraying is also called self fluxing alloy thermal spraying.

 

_self-fluxing alloy spraying is a method of using oxygen and acetylene flame to heat the coating material to a melting or semi-melting state and then spraying to the surface of the workpiece to form a solid coating. It can prepare various metals, alloys and other coatings. Due to the metallurgical bonding between the sprayed coating and the substrate material, the bonding degree between the sprayed coating and the substrate material is greatly improved, which has a very good strengthening effect of corrosion resistance, wear resistance, oxidation resistance and thermal fatigue resistance.
