Sonic spraying has excellent abrasion resistance despite its high flame rate and high density. Therefore, this kind of technology is widely used in the metallurgical industry, paper industry, packaging and printing, power supply system and other fields.
Supersonic spraying technology is referred to as HVOF, which works by transporting gas (propane) and combustible gas (oxygen) at a certain pressure and flow, igniting combustion in a high-pressure combustion chamber to form a supersonic jet, and the powder is fed into the flowing flame
Thermal spraying is the use of a certain heat source (such as arc, plasma spraying, or combustion flame) to heat powdered or filamentous metal or non-metallic materials to a molten or semi-molten state
