TL;DR: By using polarization resistance measurement and electrochemical impedance spectroscopy (EIS), in field corrosion electrochemical detections of Q235 carbon steel and Q235 ultrafine grained steel immersed samples in Zhoushan Marine Corrosion Test Station were performed for 4 years as mentioned in this paper.
Abstract: By using polarization resistance measurement and electrochemical impedance spectroscopy(EIS),in field corrosion electrochemical detections of Q235 carbon steel and Q235 ultrafine grained steel immersed samples in Zhoushan Marine Corrosion Test Station were performed for 4 years.Dynamic corrosion data during exposure were obtained.Electrochemical detection results reflected not only the corrosion modalities and corrosion rates of the samples,but also the direct influence of marine environmental factors on the corrosion behavior.Seawater temperature was the major factor influencing the corrosion behaviors of carbon steels,and corrosion rates of these samples increased with increasing seawater temperature.The influence of seawater velocity and orientation of flow was less than that of temperature.

TL;DR: In this article, the electrochemical testing technology as applied to in field corrosion evaluation of metallic materials and to study the corrosion behaviors of the materials exposed in different marine regions is presented.
Abstract: Purpose - The purpose of this paper is to research electrochemical testing technology as applied to in field corrosion evaluation of metallic materials and to study the corrosion behaviors of the materials exposed in different marine regions. Design/methodology/approach - The electrode systems for in field electrochemical evaluation of metallic samples are designed and applied to monitor two types of carbon steel samples exposed both in the submerged zone and the tidal zone at a marine corrosion test station. Corrosion potential monitoring, potentiostatic square wave, electrochemical impedance spectroscopy, and electrochemical noise methods are used in the test. Findings - It is confirmed that the electrode systems could be used for electrochemical measurement of metallic samples during exposure in the submerged zone and the tidal zone of a marine corrosion test station for long-term test durations. The electrochemical measuring results reflect the changes and differences of the samples' corrosion behavior during exposure in different regions and they respond directly to the influence of marine environmental factors on the corrosion behaviors, especially the influence of temperature. Originality/value - In this paper, lots of consecutive and dynamic corrosion information is obtained from field exposures. The findings provide a foundation upon which to investigate and forecast the corrosion behaviors of materials in marine environments.
