In this work, the open circuit potential of different stainless steel grades as well as nickel based and copper based alloys has been systematically measured in seawater under different experimental conditions. In particular the effect of temperature, oxygen content and chlorination level have been studied.
A novel evaluation technique, based on an artificial pit electrode, has been developed for inhibitor studies. The first example is of three generic inhibitors, against localised corrosion. The second is of three industrial inhibitors against existing localised corrosion on a north sea production platform
