Basic Research into the CORROSION OF STEEL IN SALT WATER

The U.S. National Bureau of Standards has recently completed a study of the electric potential needed to protect steel cathodically from corrosion in salt water. Data obtained under controlled laboratory conditions are expected to provide a basis for handling similar problems encountered under marine conditions. It was found that the best degree of protection was achieved when the specimens were held at minus 0.77 volt with reference to a saturated calomel electrode.
