The invention discloses a method for improving the abrasion resistance of the surface of an aluminum material. According to the technical scheme, the method comprises the steps that a solution system containing first particles is prepared, the solution system containing the first particles is used for conducting micro-arc oxidation treatment on the surface of a sample, the composite micro-arc oxidation film is formed, and the composite micro-arc oxidation film comprises the micro-arc oxidation film formed on the surface of the sample and the first particles dispersed in the micro-arc oxidation film; the particle size of the first particles is slightly larger than the diameter of holes of the micro-arc oxidation film, and the first particles have the same components as the micro-arc oxidation film; and laser treatment: presetting second particles on the surface of the composite micro-arc oxidation film of the obtained sample to form a ceramic powder film, and carrying out laser treatment on the surface of the
