Summary:
To investigate environmental conditions which influence the type and formation of calcareous deposits, AISI 1010 steel specimens were exposed in sea water at constant velocities and controlled potentials. Chemistry and thickness of the deposits which formed as a result of cathodic polarization of steel in sea water were determined. These variables were found to be a function of velocity and controlled potential with film thickness decreasing as velocity increased for all potentials considered. This behavior is interpreted in terms of variations in pH at the metal surface. A mass transfer analysis is presented which projects the pH at the metal surface as a function of velocity and controlled potential. Scanning electron micrographs are also included to give information regarding the nature and type of deposits. The experimental results are discussed within the frame of accepted concepts of sea water cathodic protection.
