Atlas of Polarization Diagrams for Naval Materials in Seawater.

Abstract

Polarization curves were developed in seawater at low (quiescent) flow and at 2.4 m/s flow for nine structural alloys. Potentiostatically generated curves for up to 120 days are compared with potentiodynamically generated curves at four scan rates with freely corroding pre-exposures of 1 or 120 days. Smoothed curves successfully used in computer model predictions of cathodic protection current and potential distributions are also presented. These curves are compared with previously published data available for 800 days exposure and with cathodic protection current density design guidelines. Corrosion rate data as a function of potential after up to 120 days exposure are also presented.
