The aim of the present work has been to develop a short duration test method by which it is possible to: (1) determine the necessary conditions for crevice corrosion, and (2) predict the corrosion rate in active crevices for different area ratios between free surface and crevice. The method consists of determination of cathodic and anodic polarization curves on separate cathode (free surface) and anode (crevice) specimens, respectively, by certain applied procedures. The results from short duration tests on three different stainless steels in chloride solutions have been compared with results from long duration tests, and fairly good agreement has been found. It is thought that the short duration method can be applied for determination of the most significant crevice corrosion properties. With minor adjustments, the method is also applicable for aluminum alloys in chloride solutions.
