APPLICATIONSAPPLICATIONSAPPLICATIONSAPPLICATIONS

The anodic and cathodic areas in a corrosion

cell may be due to the electrical contact of

two dissimilar metals, galvanic corrosion.

Anodic and cathodic areas may be formed on

a single metal surface as micro-cells for

instance by rain drops on uncoated steel.

Large currents can occur at small anodic

areas and lead to rapid corrosion of marine

structures such as ship's internal tanks, structures such as ship's internal tanks,

external hull plates, sheet steel piling in

harbours and tubular structures common in

jetties and petrochemical drilling and

production platforms.

Cathodic Protection is a system of preventing

corrosion by forcing all surfaces of a

structure to be cathodes by providing

external anodes.

Sacrificial anode cathodic protection

achieves corrosion prevention on a

particular structure or component by forming

galvanic cell where an additional anode of

zinc, magnesium or aluminium corrodes in

preference to the structure

The galvanic corrosion current available

from this anode / electrolyte / structure

combination should be sufficient to overcome

the local surface corrosion currents on the

structure until no current flows from anodic

areas of the structure i.e the structure is

entirely cathodic or under complete cathodic

protection.
