Re: Vibratory Tumbling
Whenever different metals are placed in a conductive liquid you create a battery. If you connect these pieces of metal together, current will flow. The current will be removing metal from one of the metal pieces = "electrolysis".
Keep in mind that electrolysis that takes place in a tumbler is minimal.
I have had the opportunity to polish parts from the same batch before and after tumbling.
The ones that get tumbled long enough for the de-burring to occur always have the micro pits. These pits are not visible until you have obtained a quality finish close to or suitable for optical imagery. So many polishers will never even notice.
