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...

Description
Summary: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. The setup was explored to simulate the galvanic performance of type 420 ferritic and type 304L austenitic stainless steels, yielding information about the anodic vs. cathodic behaviour of these materials when in close proximity to each other. The introduced approach provides a novel methodology for simulating the galvanic corrosion behaviour of stainless steels.
