The invention discloses a compressor sliding sheet surface coating. The compressor sliding sheet surface coating is of a laminated structure and is provided with a metal A transition layer, a gradienttransition layer and an alternating layer in sequence from the surface of a compressor sliding sheet to the upper part; the gradient transition layer is a graphite-like layer doped with metal A, thecontent of metal A is decreased gradually in the laminating direction, and the content of carbon is increased gradually in the laminating direction; and the alternating layer is formed by the graphite-like layer doped with the metal A and a graphite-like layer in an alternating mode. The compressor sliding sheet surface coating has the high interface bonding property and meanwhile has high hardness and high abrasion resistance. The invention provides a method for preparing the compressor sliding sheet surface coating through magnetron sputtering, the technology is simple, and industrializationis easy. 本发明公开种压缩机滑片表面涂层，该
