sacrificial anode
sacrificial anoden. An anode attached to a metal object, such as a boat or underground tank, to inhibit the object's corrosion. The anode is electrolytically decomposed while the object remains free of damage.sacrificial anode n (Metallurgy) metallurgy an electropositive metal, such as zinc, that protects a more important electronegative part by corroding when attacked by electrolytic action Translationssacrificial anode
sacrificial anode[¦sak·rə‚fish·əl ′an‚ōd] (physical chemistry) A protective coating applied to a metal surface to act as an anode and be consumed in an electrochemical reaction, thereby preventing electrolytic corrosion of the metal. sacrificial anodeA metal plate used in cathodic protection (i.e., the protection from corrosion) of piping or other equipment to which it is electrically connected. This metal plate must be more corrodible than the piping to which it is attached. |
