The invention adopts a mechanical mode and is assisted with ultrasonic excitation to induce the functional phase and the matrix material to generate in-situ phase change reaction to form the metal matrix ceramic surface or the near ceramic surface. In the process, a reconstruction tool is pressed into the surface of the alloy in a micro-pressing mode according to a set program to perform path-type rotary friction motion, so that the material is driven to generate violent plastic rheological flow, and a surface texture structure is formed; the section is gradually distorted, so that gradient seamless transition of the structure from the outer side of the structure to the substrate is realized.)
