Abstract

Reverse bend, constant deflection fatigue experiments were conducted in natural sea water at 1850 cycles per minute (cpm) to investigate the response of 1018 notched steel to concurrent cyclic loading and cathodic polarization. For comparison purposes S-log N curves were also determined in air and high purity argon. These indicate that the endurance limit established in sea water by cathodic polarization at -0.85 volts, Saturated Calomel Electrode (SCE), is greater than in either air or argon. Two mechanisms are considered as responsible for this behavior. 1. Presence of carbonate and hydroxide deposits coupled with increased alkalinity at non-propagating crack tips. 2. Adsorbed OH- layer at non-propagating crack tips.
