[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the existing metal coating surface modification technology, there are many phenomena such as uneven coating, exposed bottom, cracks on the coating surface, shrinkage holes caused by coating bridging, sagging caused by molten metal coating, weak bonding between the metal coating and the substrate, or changes in the organizational structure of the material substrate due to the coating preparation process. These phenomena cause the stability and mechanical properties of the coating to deteriorate in actual use, thereby creating safety hazards and restricting the widespread application of metal coating surface modification technology.

[0018] Compared with the prior art, the present invention achieves the following excellent effects simultaneously through the coordinated regulation of metal coating powder, substrate, process and process parameters: first, the metal coating powder is directly molded on the material surface. Because the processing time is short, no heat-affected zone will be generated on the surface or sub-surface of the material, thereby changing the comprehensive mechanical properties of the substrate material, and the coating material will not be allowed to stay at high temperature for a long time, resulting in coarsening of the structure of the coating material or deterioration of the coating material performance; second, the synergistic effect of pressure and ultrasonic vibration applied to the metal coating powder during the metal coating molding process can enable the metal coating powder to be efficiently filled into the pore position, greatly reducing the formation of coating pores, so that the coating can be molded on the substrate surface with high density; third, the molding of the coating under pressure can increase the bonding strength between the coating and the substrate, improve the service life of the coating material, and avoid the coating material from being lost due to premature peeling. effect; fourth, electric pulse rolling can be performed on the coating surface after the coating is formed, so that the coating structure is further refined and compacted to achieve a process similar to hot rolling, thereby improving the coating strength and the bonding strength between the coating and the substrate, and improving the durability of the coating; fifth, for some mixed coatings of ceramic powders and metal powders, the present invention will not cause the mixed coating powder to melt when preparing such coatings, thereby causing uneven distribution of the powder inside the coating; sixth, when the present invention processes different materials, the process parameters used are different, that is, when processing the same material, changes in process parameters will also affect the material properties. Therefore, the excellent performance of the material of the present invention is not determined by a certain process parameter, but is achieved by the coordinated regulation of metal coating powder, substrate material, process and parameters, none of which is indispensable, and only within the scope of protection of the claims of the present invention can the above-mentioned excellent effects be achieved simultaneously.
