Zusammenfassung:	The invention relates to a method for immersing the superhydrophobic surface of an aluminum alloy in one step. The method comprises the following steps of: (1) immersing the aluminum alloy in mixed solution of hydrochloric acid, long-chain fatty acid and alcohol at the bath temperature of between 30 and 70 DEG C for 5 to 25 minutes, wherein the mass ratio of the hydrochloric acid to the long-chain fatty acid to the alcohol in the mixed solution is 30-50:2-10:40-68, and the long-chain fatty acid comprises at least one of myristic acid and palmitic acid; and (2) cleaning chemically-immersed aluminum alloy through deionized water, placing the aluminum alloy in a box-type electric furnace and curing for 0.5 to 1.5 hours at the temperature of between 50 and 90 DEG C, taking the aluminum alloy out and cooling in the air. In the method, the aluminum alloy is immersed in the mixed solution of the hydrochloric acid, the long-chain fatty acid and the alcohol, and the aluminum alloy surface which has the advantages of d
