NOVELTY - The utility model claims a protective layer structure of steel bluing and graphene, comprising a steel base body, and a blueing layer prepared from inside to outside sequentially the steel base body and a graphene sealing layer. The utility model claims a protective layer structure of steel bluing and graphene, compared with the traditional preparation technique, obviously improves the wear resistance and corrosion resistance of the work piece.
