The objective of this study is to develop novel and sustainable corrosion inhibitors, which is an important and challenging task in corrosion management. This study involved the fabrication of a novel nanocomposite (NC) via the cumin-derived carbon dots (CD) mediated functionalization of an iron metal-organic framework (MOF). The MOF@CD NC was tested as a novel corrosion inhibitor for Q235B steel in 1.0 M HCl solution. The anticorrosive potential was significantly improved through the functionalization process and gravimetric tests showed an inhibition efficiency of about 98% after 72 h immersion at 25 °C with an inhibitor concentration of 100 mg/L. FT-IR and XPS analysis indicated that binding and adsorption were achieved through functional groups of MOF@CD NC. SEM and AFM studies showed significant surface damage reduction and supported the formation of a powerful protective layer in the presence of inhibitor. This research represents a significant step forward in corrosion protection technology by introducing a new class of materials with excellent performance at low concentrations, offering a promising solution for industrial applications.

Liquid phase deposition (LPD) method was used to prepare corrosion protective titanium dioxide (TiO2) film coatings on the stainless steel mesh which is composed of steel wires at a relatively low temperature (80°C). The as-prepared TiO2 coated samples were characterized using X-ray diffractometry (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray spectra (EDX). It was observed that the TiO2 film coatings could conformally coat the stainless steel wires which play a significant role in the corrosion resistance. The corrosion resistance of the samples was evaluated using Tafel polarization curves in a three-electrode electrochemical examination system. The TiO2 deposited samples all showed a certain improvement of corrosion resistance. Compared with the sample prepared in the acid condition (PH=3.7), the low alkaline (PH=9.5) sample could provide better corrosion protection which could increase the corrosion potential (Ecorr) from-0.53 V to-0.17 V.

A hydrophobic composite coating was obtained on the carbon steel surface through electrochemical deposition of a copper coating in a sulfate solution and chemical vapor deposition of a carbon fiber film. It alleviated the serious corrosion problem of carbon steel on the evaporator of hot film coupled seawater desalination system in harsh marine environment. The morphologies and compositions of the coatings were analyzed, revealing the influence of electrodeposition time on their performance. The micro-nano copper structure formed by electrodeposition significantly improved the deposition effect of carbon layer. Additionally, experiments with seawater solution contact angle tests indicated that electrodeposition transformed the surface properties from hydrophilic to hydrophobic, effectively inhibiting the diffusion of corrosive medium into the interior of the substrate. Through polarization curves, electrochemical impedance spectroscopy, and other analyses, it was demonstrated that the hydrophobic coating significantly improves the corrosion resistance of carbon steel substrates in seawater environments, surpassing the performance of traditional duplex steel.

Zn-Al layered double hydroxide (LDH) pretreatment layer was prepared by a novel two-step electrochemical method on galvanized steel surface from a precursor solution containing Al 3+ -only. In the first step, anodic currents are applied to Zn deposit to produce Zn 2+ in solution near the substrate surface. Cathodic currents are then applied to ensure the cathodic deposition of LDH film. The obtained LDH coatings not only provide excellent adhesion to the metal surface, but also enhance the adhesion between metal substrate and the top epoxy coatings. The “LDH/epoxy” painting system can protect galvanized steel from rusting for at least 150 days.

Steel rebars with oxide scale, which is usually rich of defects, are widely used in industry. On the surface of the oxide scale, it is difficult to prepare a conversion film with desirable corrosion resistance because of the acidity of conventional conversion solutions. In this work, a sol–gel solution (pH = 11) was employed to retard the diffusion of cerium ions avoiding the formation of cerium salt precipitates at room temperature. After treatments, the diffusion of cerium ions would be accelerated and a protective conversion film would form to repair natural defects on oxide scale of steel rebars at a higher temperature. This strategy can not only avoid the peeling of the oxide scale by the acid solution, but also prevent a large amount of non-uniform precipitation of the film-forming Ce 3+ ions. The conversion film@oxide scale was characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization curve (PPC) etc. It is found that the corrosion resistance of the prepared film@oxide scale was enhanced greatly when the concentration of added cerium ion (III) was 0.5 M, with pH adjusted to 11. After 30 days of immersion, R ct of surface treated rebar is more 180 times that of blank sample. The excellent corrosion resistance is closely related to the double-layer structure of the prepared sol-gel film, especially an about 2 nm inner layer of cerium oxide.

Phytic acid (PA) has a potential use as a coating on metal surface to retard corrosion. However, a loose structure and micro-cracks in the phytic acid coating layer damage the tightness of the coating, providing channels for the infiltration of corrosive media and seriously weakening the protective effect of the coating. Sodium alginate (SA) was added as an accelerating agent to improve the anti-corrosion protective effect and coating densification of the phytic acid coating on a Q235 steel surface. The micro-morphology, elemental composition and elemental chemical state of different samples were observed by the surface analysis technologies of scanning electron microscopy (SEM) equipped with X-ray energy dispersive spectrum (EDS) and X-ray photoelectron spectroscopy (XPS), all of which show a dense and homogenous phytic acid film with lower crack was precipitated on the sample treated by PA-SA conversion coating. Atomic force microscopy (AFM) and contact angle measurements were used to evaluate the adhesion properties of the prepared coating and the results showed that the PA-SA coated steel exhibited better wettability and adhesion to the top layers compared to the bare steel and phytic acid coating. The electrochemical measurements show that the corrosion resistance of the conversion coating was markedly improved on the steel substrate treated by phytic acid conversion bath containing SA.

Inspired by the self-cleaning property of the lotus leaf surface, a novel biomimetic coating with superhydrophobicity is introduced in this article. Moreover, the morphologies, crystal structures and chemical composition of the specimens were investigated using field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), energy dispersive spectroscopy (EDS) and Fourier transform infrared spectroscopy (FTIR). After electrodeposition of the Zn coating, a ZnO coating with micro and nano structures (perpendicular to the substrate surface) was obtained on an X90 pipeline steel surface after it was processed with the appropriate hydrothermal treatment time. The water contact angle (CA) of the ZnO coating, which had upright micro and nano structures, was about 137.85° without chemical modification. After further modification with a low-surface-energy material, the ZnO coating presented superhydrophobicity with the water CA of 157.59° and the sliding angle (SA) was less than 10°. Therefore, this study changed the traditional application of the deposited coating that was mostly used as a protective layer and might open up a new application field for deposited metal coatings to fabricate microstructures with functional applications, including superhydrophobic coatings.

Superhydrophilic stainless steel mesh membranes (SSMMs) with excellent antifouling, antimicrobial, and filtration performance, based on three-layer architecture, have been successfully prepared by a facile and environmentally friendly strategy. The superhydrophilic terpolymer poly(DMHB-SPP-HEA), denoted as PDSH, was synthesized through aqueous solution polymerization. PDSH-coated SSMMs (PDSH-SSMMs) were achieved by successive dip-coating of the commercial SSMMs into polyvinyl alcohol, divinyl sulfone (DVS), and PDSH solutions. The DVS layer and PDSH solution were crosslinked through DVS chemistry to enhance the hydrophilicity and provide a number of unique properties, such as antimicrobial activity, antifouling ability, and oil–water separation capability. Two different PDSH-SSMMs, PDSH0 - SSMM and PDSH5 - SSMM, were prepared and characterized using FTIR, SEM, and contact angle measurement (CAM). The antimicrobial activity, bovine serum albumin (BSA) fouling, and oil–water separation performance were evaluated simultaneously. The results indicate that PDSH0-SSMM is an excellent oil–water separation membrane for long-term separation, together with its extra antimicrobial and antifouling properties. It is promising for the industrialization of multi-functional membranes through this facile and environmentally friendly strategy.

A robust superhydrophobic surface coated with copper stearate (CS) and Fe 3 O 4 nanoparticles was prepared on stainless steel mesh (SSM) by dip-coating method for oil/water separation. The superhydrophobicity of CS@Fe 3 O 4 SSM was found to be superior to that of SSM coated with bare CS because of the enhanced surface roughness by Fe 3 O 4 nanoparticles. The CS@Fe 3 O 4 SSM shows good performance in water repellency, self-cleaning property, long-term storage, mechanical and chemical stability. And it is capable of separating various immiscible oil/water mixtures even in extreme environments (such as highly acidic, alkaline, and salty solutions) with the separation efficiency > 98% and excellent recyclability. Furthermore, various surfactant-stabilized water-in-oil emulsions were successfully separated by the CS@Fe 3 O 4 SSM due to its good superhydrophobic and superoleophilic properties as well as dense hierarchical micro/nanostructure. The preparing approach of CS@Fe 3 O 4 SSM presented in this work is facile, inexpensive and environment-friendly, which enables the CS@Fe 3 O 4 SSM to be applied in actual oil/water separation.

Steel slag (SS) contains high amounts of metal oxides and could be applied as the catalyst or support material for the reforming of biomass derived tar. In this research, steel slag supported nickel catalysts were prepared by impregnation of a small amount of nickel (0–10 wt%) and calcination at 900 °C, and then tested for the catalytic reforming of biomass primary tar from pine sawdust pyrolysis . The steel slag after calcination was mainly composed of Fe 2 O 3 and MgFe 2 O 4 , and granular NiO particles was formed and highly dispersed on the surface of nickel loaded steel slag which lead to a porous structure of the catalysts. The steel slag showed good activity on converting biomass primary tar into syngas , and its performance can be further enhanced by the loading of nickel. The yield of H 2 increased significantly with the increase of nickel loading amount, while excessive nickel loading resulted in the decrease in CO and CH 4 yields and significant increase in CO 2 yield. The presence of steam contributed to enhancing the tar steam reforming as well as reactions between steam and produced gases, while decrease the contact probability between the reactants and the active sites of catalysts, leading to a little decrease in tar conversion efficiency but significant increase in syngas yield. The iron and nickel oxides were reduced by the syngas (CO and H 2 ) from the biomass pyrolysis, and stable and porous structure was formed on the surface of the nickel loaded catalysts during tar reforming.

Corrosion seriously limits the long-term application of Q235 carbon steel. Herein, a simple fabrication method was used to fabricate superhydrophobic surfaces on Q235 carbon steel for anticorrosion application. The combination of structure and the grafted low-surface-energy material contributed to the formation of superhydrophobic steel surfaces, which exhibited a water contact angle of 161.6° and a contact angle hysteresis of 0.8°. Meanwhile, the as-prepared superhydrophobic surface showed repellent toward different solutions with pH ranging from 1 to 14, presenting excellent chemical stability. Moreover, the acid corrosive liquid (HCl solution with pH of 1) maintained sphere-like shape on the as-prepared superhydrophobic surface at room temperature, indicating superior corrosion resistance. This work provides a simple method to fabricate superhydrophobic steel surfaces with chemical stability and corrosion resistance.Keywords:carbon steel;chemical etching;superhydrophobic;chemical stability;corrosion resistance
