高温海水における鉛合金陽極の耐食性

The corrosion charactericties of lead alloy anode for cathodic protection in sea-water either in high or, in normal temperature were not yet available as the detailed reports, a sea-water intake in the normal temperature and gas condenser attached with lead alloy anode in high temperature sea-water were tested to examine the corrosive nature of respective alloys.
The results obtained are as follows:
1) Pb-Ag-Sb system electrode was best corrosion resistance both in high and in normal temperature sea-water.
2) However, in the continued electrifying, Pb-Ag-Sb, Pb-Ag-Sn and Pb-Ag alloys was not difference very little in their respective corrosion.
3) Anode electrode that containing less than 2% Ag was not stable.
4) When the amount of Sn was rich, tends to form blisters.
