I just recently began working for a company that is having issues with anodizing T6 6061, the problem that I have with the current process is that the parts are sent into the age oven after quenching with water still sitting in the parts from the quenching process. My question is how badly does oxide formation prior to anodizing effect the final product. My theory is that large amounts of oxides are being formed in some of the parts due to the supper heated H20 during aging. Then this causes galvanic corrotion problems during the etching process, leaving pits that are not properly anodizing.
