galvanic anode

(redirected from Galvanic anodes)

sacrificial anode

A 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.
