On the application of bipolar electrochemistry for simulating galvanic corrosion behaviour of dissimilar stainless steels

The application of a bipolar electrochemistry technique to simulate the galvanic corrosion behaviour of dissimilar stainless steels is introduced. The technique allows comparison of the bipolar response by controlling the extent of localised corrosion as a function of an applied offset potential. Th...
