“…After the addition of Sb, the cathodic curve in Zone I shifts obviously to the left, indicating that Sb inhibits the occurrence of the oxygen reduction reaction. This phenomenon is consistent with the results of Yang et al, [ 33 ] who found that Sb mainly affected the cathodic process of steel compared with the relatively stable anodic process. After immersion for 7 days, the corrosion potential of Sb‐free steel is reduced significantly, and the anodic process is promoted, as shown in Figure 3b.…”

The corrosion behaviors of Sb‐free and Sb‐added low‐alloy structural steels were comparatively studied in a real tropical marine atmosphere. And the role of Sb addition on corrosion resistance was clarified by electrochemical measurement and rust analysis. The results showed that the addition of 0.05% Sb increased the polarization resistance, reduced the cathodic current density, and slowed down the oxygen reduction process. Meanwhile, Sb addition optimized the physical structure, promoted the transformation of phase, and improved the protection of the rust. More importantly, 0.05% Sb addition inhibited the local acidification at the bottom of the pits, thus slowing down the local corrosion process at the rust/matrix interface. Accordingly, the corrosion resistance of the Sb‐added low‐alloy steel was enhanced, causing a lower corrosion rate than that of Sb‐free steel in a tropical marine atmosphere.

“…Yang et al [137] combined corrosion big data and machine learning to analyze the differences in the effects of microelements Sn and Sb on the corrosion resistance of structural steels. Sn and Sb inhibit the corrosion behavior of structural steels in general, and structural steels containing 0.10% Sb have the best corrosion resistance.…”

This paper provides a review of models commonly used over the years in the study of microscopic models of material corrosion mechanisms, data mining methods and the corrosion-resistant performance control of structural steels. The virtual process of material corrosion is combined with experimental data to reflect the microscopic mechanism of material corrosion from a nano-scale to macro-scale, respectively. Data mining methods focus on predicting and modeling the corrosion rate and corrosion life of materials. Data-driven control of the corrosion resistance of structural steels is achieved through micro-alloying and organization structure control technology. Corrosion modeling has been used to assess the effects of alloying elements, grain size and organization purity on corrosion resistance, and to determine the contents of alloying elements.

“…Seawater is not only constituted of salinity between 32% and 37%. Other important factors affecting corrosion are the pH value between 8 and 8.2, such as the sky value, the flow velocity, marine organisms, and other environmental elements [13][14][15]. They are also often interrelated.…”

In view of the increasingly serious problem of marine ecological environmental pollution, the traditional marine environmental corrosive pollution monitoring technology has poor monitoring accuracy and poor monitoring timeliness, and the improvement of the marine environmental corrosive pollution monitoring technology under the cloud computing platform is proposed. The research significance and corrosion influence factors of steel corrosion in the marine environment are described, and the research progress of corrosion mechanism in five different zones of the marine environment is reviewed. Cloud computing parallelizes the processing of corrosive pollution data in the marine environment through virtualization and distributed technology, which greatly improves the efficiency of the algorithm. This paper studies the existing cloud computing platform and ocean monitoring system architecture, uses the distributed architecture to design a cloud computing-oriented ocean monitoring system and meets the design requirements in data collection and data processing. The experimental results show that the precision of marine environmental corrosion pollution monitoring technology proposed in this paper is 96% on average, and the completion rate of monitoring images is 82% on average, which can effectively realize marine environmental corrosion pollution monitoring.
