Experiments prove that the double-layer full coating of the nanometer boron nitride and the nanometer borate by using the fusel oil and the poly alpha olefin in advance can obviously improve the friction performance of the new micro-lubrication material, and can effectively reduce the bearing noise and prolong the service life of the bearing after being applied to the bearing.
