Novel spinning steel collar and surface treatment technology thereof

The invention provides a novel spinning steel collar. The novel spinning steel collar comprises a steel collar base body, and the steel collar base body is coated with a first coating layer, a secondcoating layer and a third coating layer in sequence; the second coating layer comprises nanoparticles with a wearproof function and nanoparticles with a self-lubricating function. According to the novel spinning steel collar, firstly, the steel collar base body is plated with the first coating layer containing Ni-P alloy to increase the adhesion force of the second coating layer and increase the codeposition content of the nanoparticles. The nanoparticles with the wearproof function are added into the second coating layer to improve abrasive resistance of the steel collar, and through the nanoparticles with the self-lubricating function, the self-lubricating function of the steel collar is added. Finally, the steel collar is coated with the third coating layer with Ni-P alloy, small pits or small protrusions forme
