The invention relates to the technical field of aluminum substrates and discloses a method for quickly forming an oxidation film layer on the surface of an aluminum substrate. The method comprises thefollowing steps of pretreatment of the aluminum substrate, dilute nitric acid neutralization of the aluminum substrate, surface roughening treatment of the aluminum substrate, oxidation treatment ofthe aluminum substrate, acid-base neutralization of the surface of the aluminum substrate and drying of the aluminum substrate. According to the method for quickly forming the oxidation film layer onthe surface of the aluminum substrate, after the aluminum substrate is put in, an AC solution can sufficiently react with the aluminum substrate, the cleaning speed of surface grease can be accelerated, a natural oxidation layer can also be removed, it can be avoided that treatment time is prolonged as a later process is influenced, and then neutralization is carried out on remaining assisting liquid; besides, the cleaning efficiency is improved under ultrasonic cleaning, finally water drip treatment is carried out on the aluminum substrate obtained after oxidation treatment, and then drying is carried out; and in this way, the machining reaction time is greatly shortened, machining errors are reduced, oxidation rework is avoided, and the purpose of quick formation is achieved.
Description
