A sacrificial zinc anode is added in the marine heat exchanger for protecting it from corrosive salts.
This result suggests that the synergy of cathodic protection and oil extract of steel with zinc in 0.1M sulphuric acid showed a very strong adsorption bond between the oil extract molecule and the surface of the metal, which is also supported by the sacrificial zinc anode.
Protective coatings containing sacrificial zinc metal and others that act as barriers to moisture, oxygen, and salts are widely used as economical solutions.
