The invention discloses a method for preparing a graphene oxide alloy aluminium-based surface wear-resisting layer by laser cladding. In a no-water environment, hydrothermal high pressure is utilized,Ti ions are adsorbed under action of a functional group of graphene oxide, and anatase type GO@TiO2 is obtained in later-stage roasting. The obtained powder, Ti powder and glycerol are regulated andmixed in certain proportion to obtain an adhesion-state powder mixture. Matrix aluminium is grinded by abrasive paper, and the adhesion-state powder mixture is uniformly smeared on the matrix surface.A flame gun is used for quickly and uniformly pre-sintering powder on the matrix surface. Laser cladding is utilized for processing the material. The aluminium-based surface cladding material is relatively small in friction coefficient, has high surface hardness, and the like. The method has the advantages of simpleness and safety, low cost, easy operation and control, and the like.
