Abstract

In the bath the item to be plated is the cathode and there is an anode on each side. Power supplied via a rectifier is applied to the anodes periodically. During the first time period ane anodes receives a higher current than the other and in the subsequent period they change over. The time period is between 0.1 seconds to 10 minutes. Deposition time is reduced and better cover achieved. (Provisional Basic previously advised in Week 8343).
