Title:
ALUMINUM ALLOY SURFACE TREATMENT METHOD AND ALUMINUM ALLOY THEREBY
Document Type and Number:
WIPO Patent Application WO/2024/025330
Kind Code:
A1
Abstract:
An aluminum alloy surface treatment method is provided. The aluminum alloy surface treatment method comprises the steps of: processing an aluminum alloy into a predetermined shape; physically forming unevenness on the surface of the aluminum alloy which has been processed into the predetermined shape; immersing the aluminum alloy having the unevenness formed thereon in a phosphorus acid mixed solution containing phosphorus acid, sodium fluoride, and ammonium bifluoride in a predetermined mixing ratio; and anodizing the immersed aluminum alloy.
