Moreover, an experiential formula for predicting the possibilities of etch film formation in the negative half-cycle of ac has been driven from the principle of mass transfer in HCl solutions. Finally, a mechanism of ac etching for aluminum foil in HCl and a theoretical rule for choosing electroetching conditions were suggested on the results.
