Sacrificial anode of the cathodic protection aluminum-based alloy.

摘要

The invention relates to a sacrificial anode to the cathodic protection of the steels and alloys are sensitive to corrosion by seawater, operating in a field of electrochemical potential in sea water to - 870 mv to - 700 mv with reference to the potential of a saturated calomel electrode, consisting of an aluminum base alloy comprising a percentage of gallium 0,03 to 0,20% and / or a percentage of cadmium of 0,03 to 0,20%
