摘要：
A effective procedure by an interrupted reversing current has the following parameters: forward current density, 1. 4-1. 45 A/dm**2; reverse current density, 0. 5-0. 55 A/dm**2; t//f//d equals 20 sec; t//r//e//v equals 1 sec. Ammonium chloride electrolyte had the following composition (in grams per liter): zinc chloride 50, ammonium chloride 300; emulsifier OP-10, temperature 20 degree C, pH equals 5. 5-5. 6.
