cathodic protection

n
(Metallurgy) metallurgy a technique for protecting metal structures, such as steel ships and pipelines, from electrolytic corrosion by making the structure the cathode in a cell, either by applying an electromotive force directly or by putting it into contact with a more electropositive metal. See also sacrificial anode
