Embodiment 2
[0057] The corrosion-resistant aluminum alloy liner is Al-Zn-Mg-Cu ultra-high-strength aluminum alloy, and the specific components and mass percentages of the aluminum alloy: the Zn content is 9-11%, and the Mg content is 2.7-3.4%. , Cu content is 2.0-2.6%, Ce content is 0.10-0.25%, Er content is 0.05-0.15%, Zr content is 0.10-0.20%, impurity element Si content ≤0.1%, Fe content ≤0.15%, the total content of other impurity elements ≤0.15%, and the balance is Al.
[0058] The processing method of Al-Zn-Mg-Cu ultra-high strength aluminum alloy is as follows:
[0059] (1) Remove the attached dust and dirt from the aluminum alloy;
[0060] (2) Then pre-treat the surface of the aluminum alloy. The process is as follows: use degreasing treatment liquid to remove oil——water rinsing——use alkaline etching solution for alkali etching——water rinsing—use acid etching solution for acid etching—— Rinse with water - dry naturally;
[0061] The degreasing temperature of the degreasing treat...
