The
principle of impressed current cathodic protection is
in connecting an external anode to the material to be
protected from corrosion and passing of an external
( impressed ) electrical DC current.
TiTaN designs, manufacture and supply anodes for both
Impressed
Current and
Sacrificial
( galvanic ) cathodic protection system.
HSI
Impressed
current anodes are having longer life than sacrificial
anodes in cathodic protection due to their less consumption
rate, durability and strength. High Silicon Iron anodes
are also known as HSI anode or insoluble anode.
