The difficulty of replicating service-environment corrosion failure modes in accelerated laboratory testing is a well-known and well-documented challenge facing the atmospheric corrosion community. Several recent studies have highlighted the importance of cyclic variations in the test environment in recreating corrosion damage which is similar to real-world damage. A thorough understanding of the effects of these cyclic variations is critical to the development of improved accelerated tests. In this work multi-electrode arrays and corrosion sensors are used to characterize the corrosion susceptibility of metals and galvanic couples exposed to several common accelerated tests. A multi-electrode array composed of steel in an aluminum matrix is used to simulate a steel fastener in a Al 2024 panel. Spatial distributions of current are examined as a function of test environment and cycle. Using creviced sensors and multi–electrode arrays the effects of cycling humidity and temperature on crevice environments are also examined.
