Q. Hi all, Do you please know of any methods for evaluating surface preparation steps during the aluminum anodizing process other than SEM/EDS? To evaluate the rinsing, degreasing, and activation stages (impurities on the surface)... . (for example for steel plating one can use immersion in copper sulfate solution).

Thanks a lot
