Observation of corrosion behavior of stainless steels in a salt manufacturing plant environment using the multichannel electrode method

Transition of the Corrosion Protection Mechanism of Iron Partially Covered with Zinc Coating

“…10 13 and Naganuma et al applied this method to crevice corrosion of steel 14 and to the pitting corrosion of stainless steels used in salt manufacturing plants. 15 In those studies, metal samples were divided into many pieces and reconstructed to reproduce the original shape of the sample, and each piece was used as an individual electrode to measure the coupling current on it to the other electrodes to obtain a coupling current map on the corroding metals. These coupling current techniques have advantages in simple equipment and applicability to partially immersed system (wet and dry corrosion simulating atmospheric corrosion) and to large corrosion phenomena (relatively low spatial resolution) comparing to, for example, SVET.…”
