In order to study the effects of sheltering and wind patterns on local corrosivity a corrosion panel was exposed close to Highway #2, on the RMC campus, during the winter of 1999/2000. This location has an equivalent corrosivity of a seacoast during the winter because of road salt aerosols. The panel shown in the following figure was placed about 3 m above the ground on the south concrete support for the pedestrian bridge facing the highway, which was about 4m away. Six sets of CLIMAT units were deployed on the panel with each set in a different microenvironment due to either their position or the presence of shields and baffles.
One conclusion from these measurements is that shielding, whether from wind or direct precipitation, can dramatically reduce the corrosion rate of samples otherwise exposed to the same time-of-wetness factor. In fact, there was a 34-fold difference between the average mass loss in the boxed-in coupons and the reference coupon on a nearby signpost. This is consistent with the concept that atmospheric corrosion rates depend primarily on aerosol deposition rates, which in turn depend on wind velocity and turbulence patterns.
