NOVELTY - A self-lubricating plate spring comprises plate spring component and coating layer attached to surface of plate spring component. The coating layer is formed by solidifying self-lubricating coating comprising 40-55 %mass aqueous resin, 25-46 %mass additive and 9-25 %mass graphite source on surface of a steel plate spring. The graphite source comprises graphene and fluorinated graphite. The graphene content in coating is more than 6 %mass. USE - Self-lubricating plate spring. ADVANTAGE - The self-lubricating plate spring has excellent corrosion resistance, self-lubricating property, and water permeability and prolonged service life. The method improves assembling efficiency of steel plate spring. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of self-lubricating plate spring, which involves preparing self-lubricating coating, pre-treating the surface of the plate spring component, spraying self-lubricating coating on surface of the plate spring component and curing.
