Anticorrosive coatings made from polydopamine modified graphitic C3N4 composites with synergistic anticorrosion effects

Since uniform dispersion and robust interfacial compatibility of nanofiller with epoxy resin are the most critical parameters to improve the corrosion protection property, a new effective anticorrosion nanofiller [polydopamine (PDA)@g-C3N4-CeO2] is designed by stacking PDA modified g-C3N4 and nano-CeO2 with the help of a silane coupling agent. The structure and morphology of PDA@g-C3N4-CeO2 are characterized by FTIR, XRD, XPS, SEM, and TEM. Furthermore, the PDA@g-C3N4-CeO2 nanofiller is loaded within waterborne epoxy coating (WEC) and the corrosion resistance of the prepared nanocomposite coating is studied. It can be inferred from the dispersion test that g-C3N4 modified by PDA and nano-CeO2 exhibits excellent dispersion and compatibility in de-ionized water. The Electrochemical impedance spectroscope (EIS) results indicate that nanocomposite coating with PDA@g-C3N4-CeO2 exhibits the best corrosion resistance, and its low-frequency impedance (Zf=0.01Hz) is 1.78 × 109 Ω cm2, which is two orders of magnitude higher than that of pure WEC (4.27 × 107 Ω cm2). In the salt spray test, PDA@g-C3N4-CeO2/WEC also showed excellent long-term corrosion resistance with few corrosion products even after 600 h, which was consistent with the results of the EIS test. In addition, PDA@g-C3N4-CeO2/WEC also reflects the most fantastic adhesion strength (14.22 MPa), which is improved by 45.40% than that of pure WEC (9.78 MPa). Generally, the excellent protection properties of PDA@g-C3N4-CeO2/WEC are attributed to the presence of PDA and KH-550 modified nano-CeO2 on the surface of g-C3N4, which increase the compatibility and surface interactions between nanofillers and epoxy resin.

Characterization and Corrosion Protection Properties of Electrodeposited Zn–Ni–Mn Coatings

Balanced Anti-Corrosion Action of Reduced Graphene Oxide in Zn-Al Coating during Medium-Term Exposure to NaCl Solution

Considering the electronegativity and shielding anti-sepsis characteristic of reduced graphene oxide (G), we design a Zn-Al coating with embedded G (Zn-G/Al) on low-carbon steel using the low-pressure cold spray (LPCS) method. In this method, G-coated Al powders (G/Al) prepared using in situ reduction and Zn powders were mixed as a raw material for spraying. Embedding G could boost the cathodic protection performance of Zn-Al (70 wt.% zinc and 30 wt.% aluminum) coating, as has been confirmed in previous work. In this work, the microstructure, composition and electrochemical parameters of Zn-G/Al coating during full immersion were measured to investigate G’s effect on the corrosion protection properties of the Zn-Al coating. The test results showed that embedded G could facilitate the generation of many corrosion products and pile on the coating surface to form a corrosion product film during full immersion. The corrosion product film on the Zn-0.2 wt.%G/Al coating surface demonstrated an excellent protective property, which reflects the fact that the Ecorr and icorr values for Zn-0.2 wt.%G/Al after 20d immersion (Ecorr = −1.143 Vvs.SCE, icorr= 49.96 μA/cm2) were lower than the initial value (Ecorr = −1.299 Vvs.SCE, icorr = 82.16 μA/cm2). It can be concluded that adding an appropriate amount of G to the coating can balance the cathodic protection and shielding property of the coating. The equilibrium mechanism was also analyzed in this work.

Synthesis and characterization of polypyrrole‐fly‐ash‐adenosine composite reinforced epoxy coating for anticorrosive applications

AbstractPolypyrrole (PPy), PPy‐fly ash, and PPy‐fly ash‐adenosine composite in an epoxy resin system were studied for potential applications in the field of corrosion protection. The composite was prepared using a simple and cost‐effective in‐situ chemical oxidative method by interfacial polymerization technique. The synthesized composites were added into the epoxy coating matrix. All the studied formulations show excellent adhesion (5B) and good chemical resistance and passed flexibility test without any crack formation. Pencil hardness increases from 2H to 4H while scratch resistance increases from 1.5 to 2 kg for both PPy‐Ash 3wt% and PPy‐Ash‐adenosine 3 wt% as compared to plain epoxy. The contact angle observed to be 80.4° for plain epoxy and with PPy‐Ash‐adenosine 5 wt% it is 98.75°. Anticorrosive properties of the coatings were evaluated using electrochemical impedance spectroscopy bode plot analysis and salt spray tests. There was an increase in impedance from 2.5 to 4.25 ohm, as the addition of PPy‐Ash‐adenosine composite. The results indicated that the composite coatings exhibited significantly higher corrosion protection properties compared to the pure epoxy coating. The enhanced corrosion protection performance of the composite coatings was attributed to the synergistic effect of PPy, fly ash, and adenosine.

This paper presents a novel method for deriving metastable Pourbaix diagrams of Fe-Cr alloys using Density Functional Theory calculations, with the objective of providing a more comprehensive understanding of the thermodynamic equilibria within passive films, considering the metallurgical characteristics of the alloys and the electrochemical polarization conditions. By using advanced numerical tools and optimization algorithms provided by the Materials Project Database, we have developed an approach that incorporates nonequilibrium effects as a corrective factor for the chemical equilibria observed in passive films. Our findings highlight the significant role of nucleation conditions, particularly for the Cr2O3 oxide, in stabilizing the inner layers of the passive films. Lastly, the method was used to investigate the impact of pulsed polarization conditions on AISI 304 stainless steel and proposed a reaction scheme elucidating the enhanced corrosion protective properties of the passive film.

Photothermal cyclic self-healing coating with long-term corrosion protection based on bifunctional graphene

The intrinsic repair ability is a new strategy to prolong the protection life of damaged coatings, but how to maintain long-term corrosion protection during repeated healing remains a challenge. Herein, a self-healing, weather-resistant polyurethane coating with long-term stable corrosion protection enhanced by dopamine-coated graphene oxide (GP) fillers was developed. The formation of hydrogen bond between GP and the amino group in the polyurethane chain enhances the interfacial compatibility of the filler in the coating, thus improves the photothermal, thermal conductivity and barrier properties of the coating. The coating maintains excellent corrosion protection properties after 7 times of scratch-healing cycles, and can withstand up to 15 days of immersion after scratch-healing. The water evaporation rate and deicing rate of the coating are respectively up to 5.57 and 4965.5 kg/(m2·h), achieving a highly photothermal conversion efficiency. In addition, molecular dynamics simulation demonstrates that the hydrogen bonds between GP and polyurethane chains is the key factor for the excellent corrosion protection of the coating. This study opens a new avenue for improving the service life of self-healing coatings in atmospheric environment.

Mechanical and corrosion characteristics of TiC reinforced Ni-P based nanocomposite coatings

The requirement for effective corrosion protection and better mechanical properties in various industries employing metal components has led to the growth of nickel (Ni)-based metallic coatings. The electroless-synthesized nickel-phosphorus (Ni-P) nanocomposite has emerged as a particularly promising preference among other metallic coatings. This research investigates the mechanical and electrochemical performance of Ni-P coatings reinforced with titanium carbide (TiC) nanoparticles at various concentrations (0.25, 0.50, 0.75, and 1 g/L) of TiC nanoparticles. The evaluation of structural and topographical modifications caused by TiC nanoparticles introduced in the coating bath was carried out employing XRD, FE-SEM/EDS elemental mapping, and AFM techniques. Comprehensive assessments through microhardness and nanoindentation results reveal significant enhancements in mechanical properties. Additionally, erosion studies performed at various impact angles provided valuable insights into crater geometry as well as resistance against erosion. Furthermore, the highest hardness value of 665 HV0.05 was achieved at the composition of Ni-P-0.75TiC as well as electrochemical impedance spectrometry analysis shows a remarkable corrosion inhibition efficiency of 96.6% and potentiodynamic polarization inhibition efficiency of 97.99% as compared to the carbon steel substrate. As a result of their exceptional mechanical performance and good corrosion resistance, Ni-P-TiC nanocomposite coatings can be valuable options across many applications requiring adequate corrosion resistance and superior mechanical properties.

Nanoparticles are important due to their unique properties that may lead to new and exciting applications. Green synthesis has many advantages amongst physical and chemical methods of nanoparticle synthesis since the method is simple, inexpensive, and environmentally friendly. This research work describes the synthesis of carbon nanoparticles using leaf extract of Costus pictus and the characterization studies were carried out by Fourier Transform Infra-Red and Ultra Violet-Visible spectrophotometry. Incorporation of the nanoparticles of Costus pictus leaf extract into the paint formulation increases the corrosion protection properties. The inhibitive effects were investigated using weight loss, polarization, and impedance studies. The surface analysis techniques of Scanning Electron Microscope and Atomic Force Microscopy were used to investigate the morphology study. Findings show that synthetic nanoparticles mixed with paint function as more effective and thermally stable agents, serving as an alternative environmentally acceptable anticorrosion addition for cleaning and pickling processes in industries.

Recent progress in Epoxy Nanocomposites: Corrosion, structural, flame retardancy and applications — A comprehensive review

AbstractIn the past few years, epoxy resins utilization has gained much significant recognition from researchers worldwide as a result of its advantages in different sectors such as automotive, aerospace, electronic systems, constructions, and other related fields because of its outstanding mechanical performance, corrosion protection, and dielectric properties. The nanomaterials incorporation into the matrix has been duly examined to be the most productive route to enhance polymer composite's mechanical properties. Despite that, the inherent brittleness, relatively low fracture toughness, cross‐linking ability, poor electrical, and thermal properties of epoxy render it weak to growth and initiation of cracks, limiting its utilization in state‐of‐the‐art structural applications. Especially, epoxy is flammable while releasing a considerable amount of gases and smoke, thus, extending a potential risk to lives. Consequently, several nanofiller materials like graphene (Gr), transition metal dichalcogenides, MXene, and hexagonal boron nitride (h‐BN) produce extensive chances to equip multi‐functional characteristics and then reinforce the epoxy resins for the state‐of‐the‐art application. With this current review, the present literature investigation of epoxy filled with nano‐sized material has been examined thoroughly. Current advances in the approach of integrating nanosized materials in the epoxy matrices have been also introduced. Most significantly, anti‐corrosion, mechanical, and flame‐retardant properties of nanomaterials reinforced epoxy nanocomposites have also been reviewed in particular. Ultimately, the present statuses of the field in addition to the future approach have been considered concerning the usefulness of numerous nanofillers toward reinforcement of epoxy in construction and building materials. The expectation in this extensive review could produce a valuable reference, ingenuity, and guidance for researchers in this area of study.

Synergistic Effect of Nanoparticles: Enhanced Mechanical and Corrosion Protection Properties of Epoxy Coatings Incorporated with SiO2 and ZrO2.

This research paper presents the fabrication of epoxy coatings along with the hybrid combination of SiO2 and ZrO2. The epoxy resin is incorporated with SiO2 as the primary pigment and ZrO2 as the synergist pigment. The study delves into the adhesion, barrier, and anti-corrosion properties of these coatings, enriched with silica and zirconium nanoparticles, and investigates their impact on the final properties of the epoxy coating. The epoxy resin, a Diglycidyl ether bisphenol-A (DGEBA) type, is cured with a polyamidoamine adduct-based curing agent. To evaluate the protective performance of silica SiO2 and zirconia ZrO2 nanoparticles in epoxy coatings, the coated samples were tested in a 3.5% NaCl solution. The experimental results clearly demonstrate a remarkable improvement in the ultimate tensile strength (UTS), yield strength (YS), and Elastic Modulus. In comparison to using SiO2 separately, the incorporation of both ZrO2 and SiO2 resulted in a substantial increase of 43.5% in UTS, 74.2% in YS, and 8.2% in Elastic Modulus. The corrosion test results revealed that the combination of DGEBA, SiO2, and ZrO2 significantly enhanced the anti-corrosion efficiency of the organic coatings. Both these pigments exhibited superior anti-corrosion effects and mechanical properties compared to conventional epoxy coatings, leading to a substantial increase in the anti-corrosion efficiency of the developed coating. This research focuses the potential of SiO2 and ZrO2 in hybrid combination for applications, where mechanical, corrosion and higher adhesion to the substrates are of prime importance.

Fabrication of self-healable superhydrophobic polyurethane coating based on functional CeO2 nanoparticles for long-term anti-corrosion application

Corrosion of mild steel is everywhere and eco-friendly and efficient corrosion protection strategies deserve to be popularized. Superhydrophobic coatings are available for metal corrosion protection, but the limited-service life restricts their development. Here, we prepared environmentally friendly coatings with long-term corrosion resistant using a simple spray strategy. A two-layer superhydrophobic self-healable composite coating was prepared by spraying WFPU and fluoroCeNPs onto mild steel. The bottom WFPU prevents corrosion by corrosion inhibitor CeO2 and repairs physical scratches by heating. The upper layer of fluoroCeNPs prevents the penetration of corrosive media by forming an air cushion at the solid-liquid interface. The combination of low surface energy and micro/nano hierarchical structure allows WFPU/fluoroCeNPs coating to exhibit superhydrophobicity and low adhesion, with a water contact angle of 157° and adhesion force 12.8 μN. In addition, WFPU/fluoroCeNPs coating exhibit excellent corrosion resistance, with an impedance modulus of 7.2 × 109 Ω cm2 at low frequency (f = 0.01 Hz), which remains at 108 Ω cm2 after 60 days in 3.5 wt% NaCl solution. After self-healing, the material can recover to its original state, both in terms of mechanical and corrosion protection properties. This new composite coating, which combines environmental protection, energy saving and remarkable effects, has a wide application value for the protection of metal against corrosion.

Improving the polyester powder coating self-healing anti-corrosion properties via the steel surface decoration with Ce-doped-ZIF-8@ZPMn film

This study aimed to investigate the effects of ZPMn coating modification with ZIF-8 (MOF) crystals on the corrosion rate, cathodic disbonding, and adhesion properties of the polyester (Es) coating. Also, in order to increase the self-healing and adhesion capabilities of the coating in saline environments, the Es-ZPMn-MOF was modified by cerium ions (Ce3+). The treated steel's surface has been characterized using FTIR, Raman, and FE-SEM techniques. The barrier capabilities, self-healing properties, and adhesion efficiency of the polyester coating were further analyzed using Salt spray (SS), FE-SEM and EDX/mapping, EIS, Pull-off, and cathodic delamination experiments. According to the EIS results, after 24 h of immersion, the Es-ZPMn-MOF/Ce sample's (in scratched form) corrosion protection properties increased significantly (around 35%). The pull-off outcomes showed that compared to the Es sample, the polyester coating modified by ZPMn-MOF/Ce film had the most significant increase in adhesion strength and the least amount of adhesion loss (around 25%). Moreover, the cathodic delamination experiments showed that using the ZPMn-MOF/Ce film increased the Es's resistance to disbondment by 92%.

Development of waterborne anticorrosive coatings by the incorporation of coumarate based corrosion inhibitors and phosphate functionalization

Waterborne coatings are more industrially appealing for corrosion protection due to their low toxicity when compared to traditional solvent based coatings. In waterborne latex systems, the presence of surfactants is crucial, which can nevertheless contribute later to a poor performance of the final films in terms of barrier protection. This can be avoided by the use of polymerizable surfactants covalently bonded to the polymeric chains. In this work, particles of a latex loaded with an organic corrosion inhibitor, methoxy p-coumaric acid (H1), are further functionalized by the incorporation of a polymerizable surfactant, Sipomer® PAM-200 (SIP), by semibatch emulsion polymerization. The proposed system was hypothesized to ideally have higher barrier and corrosion protection properties due to the combination of H1 and SIP. However, the Electrochemical Impedance Spectroscopy results of the latexes cast on metal substrates indicate an antagonistic effect on the corrosion inhibition process rather than synergistic, as both species compete for the same moieties of the metallic surface. Thus, while the control coating with SIP (13.3 mg of SIP/g of polymer) showed impedances of 107.1–106.4 Ω and phase angles of 84–88 degrees over 24 h, the coating with H1 (3.3 mg of H1/g polymer) and SIP (13.3 mg of SIP/g of polymer) showed a less stable behavior with changes in impedances with time from 107.1 to 105.5 Ω and in phase angle from 86 to 72 degrees. The production of a bi-layer system avoids this antagonistic effect.

Electrode Potential-Dependent Studies of Protein Adsorption on Ti6Al4V Alloy.

This article presents the potential-dependent adsorption of two proteins, bovine serum albumin (BSA) and lysozyme (LYZ), on Ti6Al4V alloy at pH 7.4 and 37 °C. The adsorption process was studied on an electropolished alloy under cathodic and anodic overpotentials, compared to the open circuit potential (OCP). To analyze the adsorption process, various complementary interface analytical techniques were employed, including PM-IRRAS (polarization-modulation infrared reflection-absorption spectroscopy), AFM (atomic force microscopy), XPS (X-ray photoelectron spectroscopy), and E-QCM (electrochemical quartz crystal microbalance) measurements. The polarization experiments were conducted within a potential range where charging of the electric double layer dominates, and Faradaic currents can be disregarded. The findings highlight the significant influence of the interfacial charge distribution on the adsorption of BSA and LYZ onto the alloy surface. Furthermore, electrochemical analysis of the protein layers formed under applied overpotentials demonstrated improved corrosion protection properties. These studies provide valuable insights into protein adsorption on titanium alloys under physiological conditions, characterized by varying potentials of the passive alloy.

Effects of functionalized CNTs in improving the dielectric, corrosion protection, and mechanical properties of epoxy nanocomposites for automotive/aircraft components

ABSTRACT Excellent mechanical, thermal, electrical, electrochemical, and optical properties can be found in carbon nanotubes (CNTs). The anticorrosive and mechanical properties of CNTs in epoxy resin (EP) coatings have been improved by the integration of zirconium disulfide (ZrS2) and 2-amino−5-(4-methoxyphenyl)−1, 3, 4-thiadiazole (AMPT) for surface modification based on CNTs. The structural, morphological, and dielectric behaviors of the films were characterized for the different formulations of coatings such as EP, EP/CNTs, EP-AMPT/CNTs, EP-CNTs/ZrS2, and EP-AMPT/CNTs-ZrS2 by means of SEM/EDX, TEM, TGA/XRD, XPS, XRD, and contact angle (CA) measurement. As a result, with the addition of only 0.3% AMPT/CNTs-ZrS2, the dielectric constant of EP was increased by 87-fold at 1 Hz. The electrochemical techniques and mechanical testing confirmed that AMPT/CNTs-ZrS2 composite exhibit enhanced anticorrosive and mechanical performance of the EP coating. Superior hydrophobic property of EP-AMPT/CNTs-ZrS2 is confirmed by its WCA of 161º. Furthermore, the resistance of the EP-AMPT/CNTs-ZrS2 was found to be much higher (20.870 MΩ.cm2)] than that of the pure EP (0.112 MΩ.cm2) and the microhardness and tensile strength of EP-AMPT/CNTs-ZrS2 were increased sharply. Therefore, the newly developed EP-AMPT/CNTs-ZrS2 nanocomposite could act as the vital material for coating AA8014 aluminum alloy used in aerospace applications.

Influence of DETA on Thermal and Corrosion Protection Properties of GPTMS-TEOS Hybrid Coatings on Q215 Steel

High-performance coating could be used to protect steels in engineering. The GPTMS-TEOS hybrid coatings were successfully prepared using (3-glycidoxypropyl) trimethoxysilane (GPTMS) and tetraethylorthosilicate (TEOS) as reaction raw materials and diethylenetriamine (DETA) as both a curing agent and catalyst at room temperature. The hybrid coating contained amorphous SiO2 and was characterized by means of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The DETA content of the hybrid coating has a significant impact on the performance of the coating. As the DETA content increases, the thermal stability of the hybrid coating increases at 400–600 °C due to the production of more SiO2 in the amine-rich state. However, the gelation time decreases dramatically, preventing the hybrid coating from better infiltrating the surface of the steel substrate. In addition, there are not enough silicon hydroxyl groups to bond with the hydroxyl groups on the surface of carbon steel and adhesion is significantly reduced. Therefore, hybrid coatings with a moderate DETA content (NH:epoxy ratio equivalent to 1:1) show the best corrosion resistance, with a third-order magnitude increase in corrosion resistance compared to that of carbon steel.

Wear Resistance Research and Its 2-factor Modeling of Nanoscaled Silicon Carbide Detonation Coatings

This research is related to the spheres of wearproof coating testing. The SiC coating has been deposited on the medium carbon steel using detonation deposition using the magnet coil flux of back direction. It has been established that only nanoscaled particles are deposited on the surface which had been accumulated in aggregates of different shape. The structure of the obtained coating has been thoroughly researched on the electronic microscope in previous publication. The obtained coating has been developed for testing on the friction bench modeling the friction process that is taking place in the couple of main and rod journals of internal combustion engines. The coating has also the corrosion protection properties. The nanoscaled coating on mild carbon steel had been tested under specified conditions and their friction surfaces had been researched on electronic microscope with the view of determination of wear mechanism. The two-factor modeling of the wear rate and friction factor has been done and three-dimensional diagrams have been plotted and analyzed.

ZnO-Doped gC3N4 Nanocapsules for Enhancing the Performance of Electroless NiP Coating-Mechanical, Corrosion Protection, and Antibacterial Properties.

A carbon nitride (C3N4) nanomaterial has superior mechanical, thermal, and tribological properties, which make them attractive for various applications, including corrosion-resistant coatings. In this research, newly synthesized C3N4 nanocapsules with different concentrations (0.5, 1.0, and 2.0 wt %) of ZnO as a dopant were incorporated into the NiP coating using an electroless deposition technique. The nanocomposite coatings either ZnO-doped (NiP-C3N4/ZnO) or undoped (NiP-C3N4) were heat-treated at 400 °C for 1 h. The as-plated and heat-treated (HT) nanocomposite coatings were characterized by their morphology, phases, roughness, wettability, hardness, corrosion protection, and antibacterial properties. The results indicated that the microhardness of as-plated and heat-treated nanocomposite coatings was significantly improved after the incorporation of 0.5 wt % ZnO-doped C3N4 nanocapsules. The outcomes of electrochemical studies revealed that the corrosion resistance of the HT coatings is higher than the corresponding as-plated ones. The highest corrosion resistance is achieved on the heat-treated NiP-C3N4/1.0 wt % ZnO coatings. Although the presence of ZnO in the C3N4 nanocapsules increased its surface area and porosity, the C3N4/ZnO nanocapsules prevented localized corrosion by filling the microdefects and pores of the NiP matrix. Furthermore, the colony-counting method used to evaluate the antibacterial behavior of the different coatings demonstrated superior antibacterial properties, namely, after heat treatment. Therefore, the novel perspective C3N4/ZnO nanocapsules can be utilized as a reinforcement nanomaterial in improving the mechanical and anticorrosion performance of NiP coatings in chloride media, together with providing superior antibacterial properties.

Effects of carbon nanotubes-based composites on the corrosion protection and mechanical properties of polymer coating in chloride environment

Carbon nanotubes (CNTs) possess excellent mechanical, thermal, electrical, electrochemical and optical properties. The combination of tungsten disulphide (WS2) and 3-aminopropyltriethoxysilane (APTES) with carbon nanotubes (CNTs) has improved the anticorrosive and mechanical capabilities of poly(p-phenylenediamine) (PpPD) coatings. Scanning electron microscopy/energy dispersive X-ray analysis (SEM/EDX), Transmission electron microscopy (TEM), Thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), and X-Ray diffraction (XRD) techniques were used to characterize the composites such as APTES/CNTs, CNTs/WS2, and APTES/CNTs-WS2. As a result, the dielectric constant of PpPD was raised by 82 times at 102 Hz with the addition of just 0.6% APTES/CNTs-WS2. The APTES/CNTs-WS2 composite demonstrate improved anticorrosive and mechanical performance of the PpPD coating, according to electrochemical methods and mechanical testing. With a water contact angle (WCA) of 157°, this material is highly hydrophobic. Additionally, the PpPD-APTES/CNTs-WS2 was discovered to have significantly stronger resistance (17989 kΩ.cm2) than pure PpPD (101 kΩ.cm2), as well as significantly higher microhardness and tensile strength. The structure of the PpPD-APTES/CNTs-WS2 nanocomposite plays major role in enhancing the mechanical and anticorrosion properties. As a result, the PpPD-APTES/CNTs-WS2 nanocomposite may be used as a covering for solar panel frames.
