What are the steps in the thermal spraying process

       Except for flame spray melting and plasma arc powder non-surfacing, the formation mechanism of coatings prepared by other spraying processes is basically the same. All of them are heated by a heat source to heat the spray material to a molten, semi-molten or highly plastic state. The micro-particles in the above state impact on the surface of the substrate at high speed and deform, forming a "disk" shape. Subsequent particles will collide with particles that have already adhered to the substrate, and they will be flattened and embedded in each other, gradually forming a coating after quenching. Therefore, the process flow of various processes is basically the same, basically including the preparation and preparation of the substrate, the pretreatment of the substrate, the spraying construction, the post-coating treatment and the finishing steps.
