The invention discloses a cover plate hard coating film plating process method, which is characterized in that a nitrogen-oxygen-silicon compound is added into a coating to form a composite film layer, and the composite film layer is prepared from a high-refractive-index material layer, a refractive-index material layer and a low-refractive-index material layer which are alternately overlapped, the preparation method comprises the following steps: processing the superhard NCVM by using a dry wiping machine and covering a back adhesive tape on the front surface; plating an AF coating by using an evaporator; standing for 20 minutes at the temperature of 20-70 DEG C; manually wiping dirt on the surface of the AF and processing the back surface by using the dry wiping machine and the like. Compared with the prior art, the film has the advantages of strong mechanical property, short flow, simple post-processing procedure, no scratch and no color change phenomenon of AF technical indexes after two-hour friction, st
