摘要：
Although chloride ions have long been known to promote crevice corrosion in metals, little detailed understanding is available. In this paper, measurements of the potential, pH, and current inside the crevice, and simultaneous viewing of the crevice wall through a transparent portion of the crevice, have provided new results, and understanding of the role of chloride in promoting crevice corrosion. The results also are a proof of the potential shift theory of crevice corrosion.
