To plate gold on copper requires the copper be first nickle plated. Then the gold is plated onto the nickle. Gold will not directly plate on copper.
Sure it will! Gold plates onto copper just fine, but you have to be aware that the gold atoms are so huge that there are gaping spaces between them that will allow all manner of other atoms to pass through them and to reach the copper. The nickel acts as a reasonably inert barrier between the surface of the gold, and the copper.... think of it as being like a vapor barrier. -Chuck Harris (who worked as a gold plater for DEI as a kid) _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
