摘要

The corrosion of carbon steel in the sea-air interface area was studied by means of wire beam electrode (WBE), linear polarization (LP) technique, electrochemical impedance spectroscopy (EIS) and corrosion morphology. The WBE of carbon steel in the water-line area and under the waterline corroded seriously. The I_corr of the WBE in the two areas was the three-to ten-fold of that in the others areas. The E_corr of the WBE in the air area was higher than that of the WBE in seawater area in the experimental period. The E_corr of the WBE in the air area gradually lowered and the E_corr of the WBE in the seawater area gradually increased. The corrosion product of WBE in the seawater was fluffy and had low adhesion. The corrosion product of WBE in the air was compact and had strong adhesion. The corrosion of carbon steel in the sea-air interface area is controlled by the potential difference, dissolved oxygen concentration and corrosion product.
