Abstract
The invention relates to a soldering strengthening method for a thermal sprayed coating on the surface of a metal material. The method comprises the following steps of: firstly, spraying a solder layer on the surface of a metal material and spraying a coating needed to be prepared on the surface of the solder layer by adopting a thermal spraying method, wherein the melting point of the solder layer is lower than a coating material and a substrate material; and then, carrying out plasma plume flow heating to the surface of the coating to melt the solder layer, welding the coating and the substrate together by the molted solder layer, and cooling to generate metallurgical bonding between the coating and the substrate. In the invention, the thermally sprayed coating is strengthened by using the soldering method, metallurgical bonding is generated between the coating and the substrate, and the bonding strength (shearing tensile strength) of the obtained thermal sprayed coating is greater than 250 MPa.
