Sharing rinse between anodizing and chromating

Can we use the same rinsing tank after anodising process and alochrome process? Does it contribute any problem on the parts?

Thank you

As someone that has worked in the Aerospace industry for a few years I would consider sharing of rinses generally poor practice due to the possibility of cross-contamination. It may be considered acceptable if the water flow rate is sufficient to give very regular turnover of the water. A second, final rinse would normally be considered acceptable to be shared.

You would have to check with your customer and customer specification as to what they would allow. We Aerospace types can be a funny lot and what is acceptable to one Aeospace customer may not be acceptable to another!
