Can the composite powder composed of plastic and stainless steel be sprayed?

       The physical properties of plastic and stainless steel are very different, and many people may think that they cannot be sprayed together, but this is the powerful advantage of the thermal spraying process. The composite powder composed of plastic and stainless steel can prepare the required coating. The powder composed of plastic powder and stainless steel powder is used as the bonding primer for spraying high melting point metal, ceramic or cermet coating on the plastic substrate, so that the coating has good bonding strength with the substrate plastic. Due to the good leveling of the plastic matrix phase, the stainless steel particles are embedded in the plastic coating matrix phase to form a rough surface, which provides an ideal "anchoring" effect for the surface layer coating.



The composite powder coating of plastic and stainless steel can make the plastic maintain excellent chemical corrosion resistance, and at the same time give its surface conductivity, wear resistance, heat resistance, etc. New composite materials. Plasma spraying and powder flame spraying can be used, and the coating thickness can reach 2~3mm. The bonding strength of plasma spraying can reach 20.7MPa, and the flame spraying can reach 10.35MPa.
