The invention relates to the field of coating processing, in particular to a preparation method of a light alloy hub end face with an impact-resistant and wear-resistant coating, which comprises the following steps: 1) preparing wear-resistant coating raw material mixed powder; and (2) the powder in the step (1) is put into a cold spraying powder feeder, and a coating is prepared through cold spraying equipment. And 3) carrying out heat treatment on the obtained coating. And (4) the coating obtained in the step (3) is machined into a cylinder with threads on the side face. And (5) a circle of groove is machined in the side face of the cylindrical coating with the threads obtained in the step (4). And (6) a threaded hole is punched in the position, needing to be provided with the impact-resistant and wear-resistant coating, of the end face of the hub, and a circle of groove is machined in the side face of the threaded hole. And (7) the obtained coating with the threads is put into the threaded hole obtained in the step (6) to be fixed. And (8) a metal repairing agent is injected into a gap between the coating and the threaded hole until the groove is filled with the metal repairing agent. And (9) the hub with the wear-resistant coating obtained in the step (8) is subjected to room-temperature curing. The coating prepared through the method is high in bonding strength with the hub and long in service life.
