▎ 摘  要

NOVELTY - Spring comprises spring main body (1), which is coated with a corrosion resistant layer (3) i.e. made of corrosion resistant layer slurry, where the corrosion resistant layer slurry is prepared by mixing 20-50 pts. wt. graphene, 1-10 pts. wt. polycarbonate, 10-25 pts. wt. propylene carbonate, 15-30 pts. wt. organosilicone and 3-10 pts. wt. diluent. USE - The spring is useful for vertical damping assembly (claimed). ADVANTAGE - The spring has high corrosion resistance and wear resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing the spring, comprising (i) adding material is 60-Si2-MnA spring steel wire into the spring machine coil spring to obtain the spring semi-finished product; (ii) performing heat treatment, tempering, shot blasting, phosphating cleaning, and spraying corrosion resistant layer slurry. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the main view of the spring for vertical damping assembly. Spring main bod (1) Hook ring (2) Corrosion resistant layer (3)
