A Laboratory Technique for Evaluating Marine Splash Zone Corrosion

Abstract

An electrochemical cell and environmental chamber were developed to study corrosion in a simulated splash zone. The designs of the dual chambers and the mounting of the three electrodes in the cell resulted in an excellent simulation of the major parameters and conditions in the marine splash zone. Excellent data acquisition and corrosion observations were possible, thereby, leading to a successful laboratory technique for research on corrosion in the marine splash zone. Electrochemical corrosion measurements correlated with the progression of changes during the wet – dry cycles, and the corrosion behavior was verified by microscopic observation.
