Abstract

The invention discloses an aluminum alloy mirror surface anodic oxidation method, which comprises the following steps: S1, cleaning: placing the aluminum alloy in an ultrasonic cleaning machine, and degreasing and cleaning the aluminum alloy by a degreasing agent solution; S2, acid pickling: immersing the aluminum alloy in an acid solution to remove an oxide film layer on the surface of the aluminum alloy, after a period of time, performing neutralization treatment on the the aluminum alloy in an alkaline solution, and finally rinsing the the aluminum alloy with deionized water to remove the residual alkaline solution; S3, anodic oxidation: immersing the aluminum alloy in an electrolyte, and turning on a power supply to carry out an anodic oxidation treatment. According to the invention, through a reasonable surface treatment on the aluminum alloy before the anodic oxidation and a hole sealing treatment by a specific hole sealing agent after the anodic oxidation, the quality of an oxide film formed on the surface of the aluminum alloy is greatly improved, and the formed oxide film has good wear-resistant and anti-oxidation effects, so that the service performance of the aluminum alloy is effectively improved.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy surface treatment, in particular to an aluminum alloy mirror surface anodic oxidation method.
