Cathodic Protection Aluminum Anode
Anodes with high current output capacity.
Aluminium alloyed sacrificial anodes with high efficiency, ideal
for seawater conditions. Available in numerous shapes and sizes,
with various mounting options, suitable for all submerged
structures.
Customisation
Anodes can be customised to fit almost any requirement.
The mean current capacity of the sacrificial anode material after
12 months free running testing is 2 651 Ah/kg. The mean closed
circuit potential is -1 100 mV versus Ag/AgCl seawater.
The sacrificial anode cathodic protection method is to connect two
metals with different activities in the same electrolyte. The metal
with strong activity loses electrons and is corroded, and the metal
with poor activity is protected by electrons.
In this process, the active metal is corroded, so it is called
sacrificial anode cathodic protection. Generally, aluminum alloy
sacrificial anode and zinc alloy sacrificial anode are used in
seawater; the cathodic protection method is impressed current
cathodic protection, which is arranged through the anode In the
seawater environment, the current flows from the seawater medium to
the protected structure, and returns from the confluence point to
the power equipment. Since the current is forced to flow to the
protected structure, it is also called forced current cathodic
protection.
