✦ Synopsis

The passivation characteristics of a planar zinc electrode have been examined in 2 M KOH electrolytes containing a variety of additions. The time to passivation has been measured and compared to that of a planar cadmium electrode in 5.3 M KOH. The most promising additives were found to be borate and chromate. Auger analysis of electrode surfaces revealed possible passivating mechanisms.
