Strong combination method of metal material and plastic material

The invention discloses a treatment method of forming nano holes on the surface of an aluminum alloy and a strong combination method of a metal material and a plastic material. The treatment method comprises the following steps of: S1, selecting a workpiece and mounting the workpiece on a rack, S2, performing preliminary treatment: washing the workpiece with water, removing dust or residual fragments after machining from the surface of the workpiece, S3, performing hole preforming treatment-chemical corrosion, S4, performing hole forming treatment-electrolysis, S5, performing post treatment, and S6, performing soaking treatment to accomplish an entire experiment. The chemical corrosion is adopted during the hole preforming treatment; electrochemical corrosion is adopted during the hole forming treatment; the method is applicable to aluminum alloy materials with different strength; for example, uniform nanoscale holes are formed on the surface of a harder aluminum alloy AL6061-T6; the soaking treatment is perf
