Sacrificial anode of the cathodic protection aluminum-based alloy.

摘要

Sacrificial anode for the cathodic protection of steels and alloys which are sensitive to corrosion in seawater, operating in an electrochemical potential region in seawater from -870 mV to -700 mV with reference to the potential of a saturated calomel electrode, consisting of an aluminium-based alloy including a percentage of gallium from 0.03 to 0.20 % and/or a percentage of cadmium from 0.03 to 0.20 %.
