cell formed between steel and brass in contact with sea water results in wastage of the less noble steel. a list is given in the galvanic series, in which the more noble metals are placed in order after the less noble thus: zinc, aluminium, carbon steels, cast iron, lead—tin alloys, lead, brass, copper
, bronze, gunmetal, copper-nickel iron, monel metal. a metal in contact with one occurring later in the series, as with steel and brass, may corrode rapidly in sea water. because the action is galvanic, less noble sacrificial anodes can give protection. steel steel being subject not only to galvanic...
