Abstract
The utility model discloses an abrasion-resistant positioning pin, which comprises a positioning pin main body, wherein the positioning pin main body comprises a head and a tail; and the head is connected with the tail. The positioning pin is characterized in that a surface coating compounded with nickel phosphorus molybdenum disulfide is arranged on the positioning pin main body. The thickness of the surface coating is 5 to 7 microns. A gasket is arranged between the head and the tail. The surface coating has excellent abrasion resistance and anti-friction quality, so the abrasion between the positioning pin and a workpiece is greatly reduced, and the service life of the positioning pin is prolonged by 2 to 3 times. The positioning pin does not have any harmful component, and is safe and environment-friendly.
