The invention provides a surface treatment technology for a gear, and the technology is used for coating the surface of the gear coated with an abrasion-resisting high-strength resin coating. The surface treatment technology comprises the following steps that firstly, the to-be-coated gear is fixed in a die, when the gear is fixed to the preset axial fixing position, four penetrating holes are formed in the side, where resin is injected, of the die, three cylindrical pins are arranged on the side, where the gear is fixed, of the die, the pins penetrate the three penetrating holes in the circumferential edge of one side, where the resin is injected, of the die, and therefore the gear is embedded and fixed in the die; secondly, the die and the gear are preheated; and thirdly, molten abrasion-resisting high-strength resin is injected, after injection is finished, the die is cooled to the room temperature at the speed of 20 DEG C/h-30 DEG C/h, then, die stripping is conducted, and the abrasion-resisting high-stre
