Description
technical field [0001] The invention relates to the technical field of spraying, in particular to a low-temperature supersonic flame spraying device. Background technique [0002] Supersonic flame spraying is a kind of thermal spraying technology, that is, using a heat source to heat, melt or soften the sprayed material, relying on the power of the heat source itself or an external compressed air flow to atomize or push the melted particles into sprayed particles. The process of spraying onto the surface of the substrate at supersonic speed to form a coating. Supersonic flame spraying uses the supersonic flame flow generated by fuel (including kerosene and gas) and oxygen combustion to melt or soften the spray powder, and spray it onto the surface of the substrate at high speed to form a coating. [0003] Most of the existing supersonic flame spraying devices cannot flexibly adjust the spraying angle during spraying, and due to the high temperature in the supersonic flame s...
