dissimilar metals come into contact


two typs of cathodic protection - ✔✔galvanic and impressed current


galvanic system - ✔✔galvanic anode attached to structure


-suitbale materials include aluminum, magnesium and zinc


impressed current system - ✔✔an external power source is connected or impressed
