More Information
Summary:The invention discloses a method for avoiding Sn-Bi alloy pollution on the surface of an aluminum part, and relates to a method for removing Sn-Bi alloy pollution on the surface of the aluminum part. An anodizing layer without Sn-Bi alloy pollution is regenerated by performing alkali washing, acid pickling, chromic acid anodizing and filling treatment and setting reasonable steps and parameters, and the design requirement is met. The method effectively solves the problem of Sn-Bi alloy pollution on the surface of the aluminum part, and using reliability of the aluminum part is guaranteed.
