AB The effects of both test‐panel orientation and exposure angle on the atmospheric corrosionrates of carbon steel probes exposed to a marine atmosphere were investigated. Test samples wereexposed in a tree‐shape metallic frame with either three exposure angles of 30°, 45° and 60° andorientation north‐northeast (N‐NE), or eight different orientation angles around a circumference. Itwas found that the experimental corrosion rates of carbon steel decreased for the specimens exposedwith greater exposure angles, whereas the highest corrosion rates were found for those oriented toN‐NE due to the influence of the prevailing winds. The obtained data obtained were fitted usingthe bi‐logarithmic law and its variations as to take in account the amounts of pollutants and the timeof wetness (TOW) for each particular case with somewhat good agreement, although these modelsfailed when all the effects were considered simultaneously. In this work, we propose a newmathematical model including qualitative variables to account for the effects of both exposure andorientation angles while producing the highest quality fits. The goodness of the fit was used todetermine the performance of the mathematical models.
