: Is it best practice to chemical conversion coat (MIL-C-5541D) aluminum(6061-T6) before hard anodizing (MIL-A-8625F)?
Just before anodizing? No.
If it is to be anodized, the surface must be free of any coating. That means if it has chem film, this has to be stripped first before being hard anodized.
