Summary: This study evaluates galvanic corrosion induced by FeCO3 and Fe3C layers on carbon steel surfaces when coupled to bare carbon steel. The study finds that the Fe3C-filmed carbon steel acts as the net cathode, significantly enhancing corrosion rates of bare steel. Galvanic currents induced by FeCO3-filmed steel are much lower, with FeCO3 being removed from the surface as Fe3C is revealed on bare steel.

Summary: The development of crevice corrosion is closely related to changes in the microchemical environment in crevices, which is difficult to detect using conventional electrochemical techniques. A Pt/IrOx-pH ultramicroelectrode was developed to study the local radial pH distribution in crevices, showing excellent sensitivity and stability. This technique can be used to explore the mechanisms of crevice corrosion and the early stages of pitting corrosion.

Summary: Through experiments, it was confirmed that the passive film has an influence on the tribocorrosion behavior of stainless steel. Different pH values of the solution can cause different passive states. The pure wear behavior in air is dependent on the applied load, while the tribocorrosion in deionised water is smaller than the pure wear in air. Furthermore, the tribocorrosion is stronger in acid solutions compared to neutral and alkaline solutions.
