Lead/platinum anodes for marine applications Available to Purchase

Tests have been carried out on lead/platinum bielectrodes in sea‐water at 50 A/ft2 for one year to determine the effect of lead alloy compositions on the growth of the lead peroxide. The results indicate that small additions of tellurium or bismuth to a 1 % Ag/Pb alloy are effective in reducing the formation of lead peroxide. Lead/platinum bi‐eleetrodes of suitable lead‐alloy composition, are considered to provide an inexpensive anode material for power‐impressed cathodic protection systems for marine applications.
