cathodic protection

[kə′thäd·ik prə′tek·shən]
(metallurgy)
Protecting a metal from electrochemical corrosion by using it as the cathode of a cell with a sacrificial anode. Also known as electrolytic protection.

cathodic protection, electrolytic protection

A method of protecting a ferrous metal structure, which is embedded in water or moist soil, from corrosion due to galvanic action; usually by attaching it to a metal rod which is more electronegative than the structure, or by counteracting the current which is the source of corrosion by another one (in the opposite direction) which just balances it.
