Zn-Phosphatization of Aluminium

2007

Hi,

We are currently using a Zn-phosphatization conversion for aluminium parts. For etching there is a concentration of Fluorine present.

For a new project, we have some corrosion problems on these parts. According to the CASS-test(Copper acid salt spray)our process isn't feasible.

Has anyone have experience with this kind of problem?
