“…Corrosion of steel facilities in harsh marine environment is severe. − Some studies have pointed out that sun illumination can be involved in the corrosion process. It is attributed to the semiconductor properties of the corrosion products, which influence the corrosion process by generating a photocurrent .…”

Photocathodic protection technology has presented great potential for protecting stainless steel; however, due to the higher electrochemical activity and more negative corrosion potential of carbon steel, most of them are not applicable to carbon steel. This study has fabricated a series of TiO2/Au/CdS nanostructured coating. The prepared samples have extended light absorbance to the visible light region. Among then, the TiO2/Au10/CdS nanostructured coatings have successfully offered cathodic protection to carbon steel. The maximum photogenerated potential drop value is −0.591 V, and the photocurrent density is 1.253 mA·cm–2, which is about 4 times higher than that of TiO2. The active species trapping tests have been performed to reveal that the nanostructured coatings possess a Z-scheme heterojunction property, which supplies an efficient charge separation and demonstrates strong reduction and oxidation abilities. The photocathodic protection mechanism is discussed in detail in the paper.

“…In Figure b, the copper on the superhydrophobic coating without corrosion appears as CuO (934.67, 952.65, and 954.70 eV) and Cu 2 O (932.85 eV), which can fix fluorosilane to the surface and thus reduce the surface energy. The peaks of the corroded coating, in Figure d, are analyzed and subsequently identified as Cu(OH) 2 (935.08 eV), CuO (954.70 eV), and Cu (933.04 eV). − This indicates that copper oxide on the surface is destroyed, resulting in the exposure of the pure copper matrix and the formation of corrosion products. Simultaneously, in Figure e, there is a noticeable peak of Mg(OH) 2 binding energy at 49.51 eV on the corroded surface .…”

Corrosion is an unavoidable issue that steel encounters during service; however, the generic methods employed for corrosion prevention often need high cost or preparation conditions. In this study, a facile chemical replacement deposition method was proposed to realize an anticorrosion superhydrophobic coating on a X80 steel surface. The growth mechanism of the rough structure and its impact on the wettability of the superhydrophobic coating were analyzed. The superhydrophobic coating, deposited for 50 s and modified for 30 min, achieved optimal electrochemical properties and a maximum water contact angle. The immersion test, in the saturated CO 2 oilfield produced water, demonstrated the better corrosion resistance of superhydrophobic coating than X80 steel. Correspondingly, a kinetic corrosion model was established to analyze the anticorrosion mechanism. In summary, this method significantly improves the corrosion resistance of X80 steel and is attractive for other industrial fields.

“…Figure 6 illustrates the variation of the Tafel slope (absolute value) over time under different operating conditions. Notably, irrespective of the operating conditions, the absolute value of the cathode slope consistently surpasses that of the anode, suggesting that the corrosion process of carbon steel under the iron bacteria system is primarily governed by the cathode [35][36][37]. Furthermore, the cathodic curve of the IB+HEDP condition exhibited a significantly higher slope than that of the IB condition throughout the experiment, indicating that cathodic inhibition is the primary corrosion inhibition mechanism of HEDP.…”

Regenerated water serves as a supplementary source for circulating cooling water systems, but it often fosters microbial growth within pipelines. Given its widespread use as a corrosion inhibitor, understanding HEDP’s efficacy in microbial environments and its impact on microorganisms is imperative. This study established an iron bacterial system by isolating and enriching iron bacteria. Through a comprehensive approach incorporating corrosion weight loss analysis, XPS analysis, SEM electron microscopy, as well as microbial and electrochemical testing, the corrosion inhibition behavior and mechanism of HEDP within the iron bacterial system were investigated. The findings reveal that within the iron bacterial system, HEDP achieves a corrosion inhibition rate of 76% following four distinct stages—weakening, strengthening, stabilizing, and further strengthening—underscoring its robust corrosion inhibition capability. Moreover, HEDP enhances the density of biofilms and elevates the activation energy of carbon steel interfaces. It alternates with oxygen to continuously suppress the activity of IRB while gradually inhibiting the activity of IOB. This process culminates in a corrosion inhibition mechanism where cathodic inhibition predominates, supported by anodic inhibition as a complementary mechanism.
