“…In Figures 1(a), (b) and (c), OM images indicate that all steels consist of ferrite phases (white areas) and pearlite colonies (dark areas). However, the volume fraction of pearlite increased from 0.8% to 6.8% because of the increasing content of Cr that could form Cr x C y phases (Riebisch et al , 2018; Zhou et al , 2018; Wang et al , 2022a, 2022b). Moreover, the grain size measured by an intercept method was about 23.0, 22.5 and 22.9 μm for Cr 0 , Cr 0.5 and Cr 1.0 steels, respectively, suggesting that alloyed Cr had a limited effect on refining grains.…”

“…High-strength low-alloy steels that are widely used in marine engineering mainly exhibit a ferrite-pearlite microstructure (Lgwemezie and Mehmanparast, 2020;Wu et al, 2020;Lgwemezie et al, 2021;Wang et al, 2022aWang et al, , 2022bGong et al, 2016;Li et al, 2022). Because of the adverse effects of the multiphase structure, they are susceptible to corrosion during service.…”

Purpose The poor corrosion resistance of the ferrite-pearlite steel limits its application in marine engineering because of the enhanced galvanic effect caused by continuously accumulated cementite. Cr as one principal alloying element is commonly used to improve the corrosion resistance of steels. This paper aims to study the effect of Cr on corrosion behaviors of ferrite-pearlite steels in an acidic environment. Design/methodology/approach The tested steels were immersed in a simulated solution of 10 Wt.% NaCl with pH 0.85 for 72 h to evaluate the corrosion rate. After the immersion test, the corrosion morphologies and products were tested by scanning electron microscopy, energy dispersive X-ray analysis and X-ray diffraction. Meanwhile, an electrochemical workstation was used to study the electrochemical behaviors of samples. Findings At the initial corrosion stage, the corrosion rate increased in the sequence of Cr0, Cr0.5 and Cr1 steels, which was because of the competitive effect between the area ratio and the driving force caused by alloyed Cr. However, Cr1 steel exhibited the best corrosion resistance after a 72-h immersion test. This was because the alloyed Cr promoted the formation of protective Fe2O3 and FeCr2O4, which suppressed the preferential dissolution of ferrite and, thus, reduced the accumulation rate of carbides, resulting in the weakened galvanic corrosion. Originality/value This paper reports the role that Cr plays in the galvanic corrosion of ferrite-pearlite steels, which is important for the engineering application of ferrite-pearlite steels in marine environment.

“…The seawater could flow into the barnacle shell from the corroded meshes, thus resulting in the enrichment of chloride ions. However, it is found in other researches (Murugan et al, 2020;Messano et al, 2014) that a calcium layer might form beneath the macro-foulers which sometimes could mitigate the general corrosion rate (Wang et al, 2022a(Wang et al, , 2022bMa et al, 1995). The marine environment, water quality and the types of pollutants all have dramatic influences on the macro-fouling corrosion (Xu et al, 2022;Zhang et al, 2017).…”

“…The marine biofouling is one of the most significant and tough issue for the initiation and propagation of localized corrosion in natural seawater (Liu et al, 2022). Various studies were conducted in past decades to understand the localized corrosion of stainless steel caused by macro-fouling (Wang et al, 2022a(Wang et al, , 2022bVedaprakash et al, 2013). It is found that the localized corrosion is normally induced by the colonization of hard foulers such as the mussels, oysters and barnacles on the steel surface (Blackwood et al, 2017;Wang et al, 2022aWang et al, , 2022b.…”

Purpose The purpose of this paper is to study the interaction of main marine organisms on localized corrosion of 316L stainless steel in the Dalian Sea area. Design/methodology/approach The steel plate was immersed in the Dalian Sea area for nine months to observe the biofouling and localized corrosion. The local potential distribution on the steel plate covered by marine organisms was measured. The local electrochemical measurements were performed to facilitate understanding the interfacial status under different biofouling conditions. The local surface morphologies and corrosion products were characterized. Findings The localized corrosion of stainless steel is mainly induced by the attachment of barnacles on the steel. The mussels have no influence on the localized corrosion. The cover of sea squirts could mitigate the localized corrosion induced by barnacles. Both crevice corrosion and pitting corrosion were found beneath the barnacle without the covering of sea squirts. The pitting damage was more serious than the crevice corrosion in the Dalian Sea area. The probing of sulfur element indicates that the potential growth of sulfate-reducing bacteria at barnacle center. Originality/value The above findings revealed that the interaction of marine organisms has significant influences on the localized corrosion of stainless steel. The influences of macro-fouling and micro-fouling on localized corrosion are discussed.
