| 英文摘要 | The atmospheric corrosion of carbon steel is an extensive topic that has been studied by many authors who have proposed many mechanisms and techniques for studying the phenomena involved and have reported long term exposure data in many different regions throughout the world. However, there are few literatures that have discussed the corrosion results of carbon steel exposed for short-term time which can contribute to the understanding of the initial corrosion mechanisms. Therefore in this work, mass-loss measurement, SEM, XRD, infrared spectroscopy and electrochemical techniques have been used to investigate the initial corrosion evaluation of carbon steel exposed to a coastal-industrial atmospheric environment in Hongyanhe. Mass-loss results show that the short-term corrosion kinetic of carbon steel is in good fitting with linear function, and the average corrosion rate fluctuates over time and don't show the downward trend observed in long-term exposure experiments. Lepidocrocite, goethite and magnetite are identified in corrosion products formed on the surface of exposed carbon steel samples. The content of lepidocrocite shows a decreasing trend over exposure time, while goethite is the opposite. Magnetite appears in the later stages and keeps stable in amount. Pitting and an irregular localized corrosion can be observed clearly on the surface of carbon steel specimens exposed for 10 d. The corrosion product at pitting regions is circular flowery shape which varies in details as the physical and chemical environments change. The rust layer grows over time and eventually covers the entire surface of carbon steel samples exposed for more than 60 d, yet its thickness is uneven. The surface of rust layer has many nest-shaped structures that can't barricade the physical transmission effectively. The protective effect of rust layer has been further discussed in combination with electrochemical results. |
