金属粉末热喷焊法是应用特殊的喷枪,通过氧-乙炔火焰,将自熔性合金粉末喷敷到经过清理的零件表面,然后用同一火焰或另外的热源,将粉末敷层加热重熔并与基体达到原子扩散结合,获得牢固的喷焊层。 Metal powder thermal spray welding method is the use of special spray gun, the oxygen - acetylene flame, the self-fluxing alloy powder sprayed to the surface of the cleaned parts, and then use the same flame or another heat source, the powder coating heated remelted and And the matrix to atomic diffusion combined to obtain a solid spray coating.
