A High-Throughput Test Methodology for Atmospheric Corrosion Studies

Abstract

This letter presents a high-throughput methodology to systematically study individual variables involved in atmospheric corrosion. Corrosion caused by droplets, representative of various atmospheric environments, was quantified in terms of volume loss as measured through optical profilometry. Measurements were sensitive to variations in electrolyte chemistry and allowed relatively rapid and reproducible discrimination between the effects of different atmospheric parameters. This approach allows a high degree of experimental control and calculated corrosion rates from optical profilometry were comparable to those obtained using an independent electrochemical method.
