“…The inclusion of a limited quantity of rare earth elements has a relatively minor impact on the overall fabrication cost. Laboratory studies have demonstrated that incorporating cerium into steel can lessen microbial corrosion, but there is a dearth of practical assessments regarding the antibacterial efficacy of rare earth metals on authentic microbial corrosion communities (Jing et al, 2007 ; Yin et al, 2021 ; Yuan et al, 2013 ).…”

The global economic burden of microbial corrosion of metals is enormous. Microbial corrosion of iron‐containing metals is most extensive under anaerobic conditions. Microbes form biofilms on metal surfaces and can directly extract electrons derived from the oxidation of Fe0 to Fe2+ to support anaerobic respiration. H2 generated from abiotic Fe0 oxidation also serves as an electron donor for anaerobic respiratory microbes. Microbial metabolites accelerate this abiotic Fe0 oxidation. Traditional strategies for curbing microbial metal corrosion include cathodic protection, scrapping, a diversity of biocides, alloys that form protective layers or release toxic metal ions, and polymer coatings. However, these approaches are typically expensive and/or of limited applicability and not environmentally friendly. Biotechnology may provide more effective and sustainable solutions. Biocides produced with microbes can be less toxic to eukaryotes, expanding the environments for potential application. Microbially produced surfactants can diminish biofilm formation by corrosive microbes, as can quorum‐sensing inhibitors. Amendments of phages or predatory bacteria have been successful in attacking corrosive microbes in laboratory studies. Poorly corrosive microbes can form biofilms and/or deposit extracellular polysaccharides and minerals that protect the metal surface from corrosive microbes and their metabolites. Nitrate amendments permit nitrate reducers to outcompete highly corrosive sulphate‐reducing microbes, reducing corrosion. Investigation of all these more sustainable corrosion mitigation strategies is in its infancy. More study, especially under environmentally relevant conditions, including diverse microbial communities, is warranted.

At present, there are few studies on microbial corrosion of magnesium anode materials that provide protection for oil pipelines in tidal flat environment. In view of an abnormal failure of magnesium anodes in oil pipelines in a tidal flat mud environment, the influence of the change in water content in the beach mud on the corrosion of AZ31B magnesium anode by sulfate-reducing prokaryote (SRP) was investigated by electrochemical methods, weight loss and surface analysis techniques. SRP can grow well in a tidal flat mud environment and cause microbial corrosion of magnesium alloy. The results show that with the increase in water content, the number of SRP cells in the mud increased, that the corrosivity of tidal flat muds was enhanced and that the corrosion rate of AZ31B magnesium anode was accelerated: compared with the corrosion rate of 0.554 mm/y in 40% water content, the corrosion rate of magnesium alloy samples in 60% water content is as high as 1.38 mm/y.

“…Scholars have discovered that adding an appropriate amount of rare earth elements (La and Ce) to steel can improve the corrosion resistance and wear resistance of structural steel, as well as extend its life cycle. Existing research can fully explain the benefits of incorporating rare earth elements [1][2][3][4][5][6][7]. However, recent research has revealed that the alloying process of rare earth elements, as well as the problem of nozzle clogging in rare earth steel, are still significant issues that impede the efficient utilization of rare earth elements.…”

The formation mechanism of the clogging layer of the alumina-carbon submerged entry nozzle in the smelting process of rare earth Q355 steel was investigated in this paper. First, the inclusions in the molten steel were discovered to be primarily composed of CaAl 2 O 4 , MgO, CaS, and CeAlO 3 . The mass fraction of solid inclusions increases as the rare earth content increases, and the proportion of inclusions, primarily CaAl 2 O 4 , changes. Calcium titanate and cerium aluminate formation can be inhibited by high [Ca] content. XRD and scanning electron microscopy were then used to examine the phase composition and morphology of the inner and outer arcs of the clogging nodules. The clogging was found to be divided into three layers: the nozzle matrix, the reaction layer, and the steel layer. Finally, it is concluded that the dissolution of C element in refractory material is the cause of nozzle blockage, and the core cause of nozzle blockage is the deposition of Al 2 O 3 , CaAl 2 O 4 , and rare earth compounds. Meanwhile, solutions to nozzle blockage are provided from the perspectives of top slag optimization, the deoxidization process, the calcium treatment process, and protective pouring.
