Abstract
The profile of an electrolytically-thinned metal foil is largely determined by the combined effects of electric and gravitational fields. Uniform thinning can be approached by making the applied electric field as uniform as possible and by utilizing some kind of stirring to counteract the variation in viscous anode layer thickness caused by gravity. Gas evolution at the sample may also play an important role in the process. Because of the ionic nature of electrolysis, it might be expected that applied magnetic fields of appreciable strength should produce significant changes in the process due to the Lorentz force on charged particles. Preliminary experiments have shown that this is the case. The net effect of these changes in the experiments thus far has been to enhance the uniformity of thinning.
