Electroplishing to remove embedded abrasives in 304 Stainless Steel?
(OP)
Hello, We have about 100 canisters made from 304 SS that have been abrasively ground, sanded and/or polished. The exact type/brand/composition of abrasives used is not in our control since an outside vendor is doing this part of the work. They will undoubtedly use whatever they have at hand.
As a final step we need to remove any embedded abrasives (and any binder used to hold the abrasives together) from the 304 SS. We think that electropolishing may accomplish this, but I can't find any information on how successful we should expect this to be. Does anyone have any data on how well elecroplishing will remove embedded abrasives? If the embedded abrasives go deeper than .0005" will electropolishing get them out? Any source of hard data on this would be greatly appreciated.
These canisters will be going in a high vacuum environment in which there are instruments that are very sensitive to even the smallest contamination. Particularly from any out-gassing of any compounds that might have gotten embedded with the abrasives. Before going into the vacuum the canisters will also undergo ultrasonic cleaning and vacuum baking for 48 hours to remove any remaining surface contamination, and then handled only in a class 100 clean room environment.
thanks for your help

My quick answer would be to get one of what you consider the worst cases and one of not so bad and have them electropolished polished.
One approach is to contact people like Extrude Home who have a multifaceted approach to surface finishing.

May I ask how you are determining that you have embedded abrasives?

The follow-on question will be the same for 6061-T6 AL plates that have been sanded.
