Embodiment 1
[0024] A surface treatment method for an aluminum alloy material, comprising the steps of:
[0025] (1) Surface pretreatment:
[0026] First use sandpaper to polish the surface of the aluminum alloy material, then rinse the surface with deionized water, and finally put it in a drying oven for 1 hour and take it out for later use;
[0027] (2) Laser treatment:
[0028] Put the aluminum alloy material processed in step (1) into the laser processor for laser scanning radiation treatment, and take it out for later use;
[0029] (3) Passivation treatment:
[0030] Put the aluminum alloy material treated in step (2) into the passivation solution for passivation treatment, heat and keep the temperature of the passivation solution at 65°C, and continue to apply ultrasonic treatment at the same time, take it out after 45 minutes for use; the passivation The solution is composed of the following parts by weight: 7 parts of fluozirconic acid, 5 parts of fluotitanic acid, 6 parts of ph...
