Multiple advantages of Ti 3 C 2 T x MXene are of significance to enhance the mechanical properties of organic coating . Herein, few-layer amino-functionalized Ti 3 C 2 T x nanosheets (k-Ti 3 C 2 ) were introduced into interpenetrating polymers network (IPN) for constructing k-Ti 3 C 2 /IPN composite coatings , and their tribological properties were investigated in depth. The composite coating with 0.75 wt% k-Ti 3 C 2 nanosheets displays excellent tribological behaviors under extremely operating conditions, like the lowest COF (0.18) and the highest OCP value (−0.28 V) under tribocorrosion condition. Such excellent tribological properties mainly depend on good dispersion and interfacial compatibility of k-Ti 3 C 2 nanosheets in IPN matrix, as well as amino functionalized Ti 3 C 2 T x nanosheets as barrier to external damage. This work highlights a pathway to solve the wear/corrosion problem of organic coatings under extreme conditions.

Digital light processing (DLP) has been widely utilized in ceramic additive manufacturing, while research on its application for fabricating metallic materials remains in the initial stages. In this paper, the geometric accuracy, mechanical and tribocorrosion properties of AISI 316 L prepared by DLP (DLP-316L) are systematically evaluated. DLP technology exhibits high forming accuracy in additive manufacturing of metal parts, with dimensional errors controllable within ± 70 μm and surface roughness of 1.6 μm. The microstructure of DLP-316L comprises austenite with minor δ-ferrite and M 23 C 6 /M 7 C 3 carbides. The carbides originate from residual carbon due to incomplete decomposition of photosensitive resin during debinding, while δ-ferrite forms during prolonged high-temperature sintering at 1380 °C for 6 h. It not only has a high ultimate tensile strength of 543.5 MPa, but more importantly, the fracture elongation can reach 58.73 %, which is at a high level in the preparation of AISI 316 L using DLP. In addition, the tribocorrosion performance of DLP-316L in 3.5 wt% NaCl solution is better than that of the commercial as-rolled AISI 316 L. This is mainly attributed to the presence of a small amount of high-hardness carbides in the microstructure, which improves the wear and corrosion resistance of the material.

To improve the tribological performance and corrosion resistance of engine bearings exposed to contaminated lubricating oil , polymer coatings containing NdCl 3 at concentrations of 3.45 wt%, 5.17 wt%, and 6.89 wt% were developed, respectively. These coatings were applied to the surfaces of copper and aluminum alloys using a liquid spraying technique, aiming to assess their corrosion and wear resistance. Electrochemical experiments showed that the coating with a 3.45 wt% NdCl 3 concentration exhibited superior corrosion resistance , as evidenced by the highest self-corrosion potential and polarization resistance. Furthermore, friction tests on the corroded samples revealed that the 3.45 wt% NdCl 3 coating also demonstrated the lowest coefficients of friction and wear rates. This is due to the addition of an appropriate amount of NdCl 3 , which densifies the internal structure of the coating and improves the mechanical properties of the coating, thereby significantly improving its corrosion and wear resistance.

Corrosion and corrosive wear occur commonly on metals surface in aqueous solutions. External electric field is usually considered as one of the factors to accelerate corrosion or corrosive wear of materials in the presence of conventional electrolytes. This work aims to reposition widely believed perspective by experimental justification which have been conducted in aqueous solutions containing surfactants. Electric potential of metal surfaces was modulated externally within the electrochemical potential window of the metal electrode-solution-counter electrode system, which actively regulated the adsorption or desorption of surfactant molecule in the aqueous solution over the electrodes to form a molecular barrier of electron transportation across the electrode-electrolyte interface. The advantage of the approach over the anodic passivation is negligible redox reactions on the protected electrode surface while a better lubricious and wear resistant film than oxide is maintained in the meantime. Tribopairs of several metal/metal and metal/ceramic were tested by employing a ball-on-disc tribometer with anionic and cationic surfactants solutions. For anionic surfactant as the modifier, positive surface potential enables coefficient of friction to be decreased by promoting the formation of adsorption film on metal surface in aqueous solutions. For cationic surfactant, negative surface potential plays a role in decreasing the coefficient of friction. Phase diagrams of friction and wear in wide ranges of surfactant concentration and surface potential were plotted for the tested metal/metal and metal/ceramic tribopairs. These results indicate that the adsorption behavior of molecules or ions at the metal-aqueous interface can be well regulated when an external electric field is present without inducing corrosion or corrosive wear.

2D MXene@ZIF is synthesized by inducing nucleation and interlayer confinement growth. • Nano-heterostructure suppresses restacking and enables interlayer shear lubrication. • ZIF-L component increases the crosslinking density and effective corrosion inhibition. • PMX@ZIF/EP coating showed rising OCP, stable friction and low wear in tribocorrosion. To enhance the tribocorrosion resistance of epoxy (EP) coatings, a layered MXene@ZIF heterostructure was synthesized and subsequently oriented into a parallel-aligned polyethylenimine-modified MXene@ZIF composite coating (PMX@ZIF/EP) on an AA2024 substrate via electric field-induced alignment. During heterostructure synthesis, the pre-anchoring of 2-methylimidazole on the Ti 3 C 2 T x MXene surface induced high-density nucleation and confined interlayer growth of ZIF-L nanosheets, effectively suppressing MXene restacking while preserving interlayer shear lubrication. In the dry sliding test, PMX@ZIF/EP exhibited a wear rate of 3.33 × 10 −5 mm 3 ·N −1 ·m −1 , approximately 75% lower than that of pure EP. Furthermore, the ZIF-L component increased the crosslinking density of the epoxy matrix and contributed to corrosion inhibition. After 4 weeks of electrochemical testing, PMX@ZIF/EP maintained the highest |Z| 0.01 Hz value of 1.59 × 10 10 Ω·cm 2 , demonstrating excellent long-term protective performance. Under coupled tribocorrosion conditions, the coating exhibited a progressive positive shift in open-circuit potential. Through the in situ formation of a dense, parallel-aligned tribofilm, the composite coating stabilized the friction coefficient at 0.28 and reduced the wear rate to 2.78 × 10 −5 mm 3 ·N −1 ·m −1 . This synergistic integration of active-passive protection and interlayer shear lubrication provides an effective strategy for extending the service life of aluminum alloys in severe environments.

With the development of deep-sea exploration technology, the technology of fire-retardant hydraulic fluid (HFC) has played an important role in the power transmission of exploration equipment. However, the mechanism of the influence of seawater content on the tribocorrosion behavior of HFC remains unclear. In this study, the effects of different seawater contents on the tribological and corrosive properties of HFC were systematically investigated. The results showed that when the seawater concentration exceeds 30 wt%, a soft Mg-containing reaction film is formed in the friction contact area owing to seawater corrosion, thus effectively improving the sintering load and wear resistance to some extent. By contrast, with increasing seawater concentration, the lubricity declines, the wear intensifies, and the extreme pressure characteristics decrease significantly. The comparative analysis shows that the composition of the wear and corrosion reaction films significantly differs under high-concentration seawater conditions, which is also a key factor affecting the friction and corrosion behavior of HFC. This study provides a direction for the research and development of wear- and corrosion-resistant materials and coatings on the surface of deep-sea exploration equipment.

This study is aimed at the enhancement of the corrosion and tribocorrosion performance of AZ31B magnesium (Mg) alloys after plasma electrolytic oxidization (PEO) treatment. Some PEO-treated Mg samples were coated with chitosan (CS) film by dip-coated method, while others were subjected to hydrothermal treatment (HT) followed by CS film. The microstructure and chemical composition of coatings were investigated via X-ray diffraction, scanning electron microscopy, and Fourier transform infrared spectroscopy . Corrosion resistance of the specimens was evaluated via electrochemical measurements (open circuit potential and electrochemical impedance spectroscopy) in simulated body fluid. The tribocorrosion performance was determined by simultaneously recording the variation of the friction coefficient and the open circuit potential with the sliding time. The results indicated that better corrosion and tribocorrosion performance were observed when CS layer is applied on hydrothermally treated PEO samples than on the bare PEO samples. Thus, fabrication of hydrothermally treated PEO surface coatings with chitosan is a significant approach to protect the Mg from corrosion and tribocorrosion, thereby increasing the potential application of Mg alloy as biological implants .

Interest in slippery liquid-infused porous surfaces (SLIPSs) has grown considerably for anti-icing, anti-corrosion, and wear resistance owing to their unique structure and outstanding performance. In a loss of lubricant condition in service, however, the surface of a material sees its durability become deteriorated. In this work, laser processing and hydrothermal treatment were developed to fabricate a slippery liquid-infused porous surface (SLIPS) with durable anti-corrosion and anti-tribocorrosion properties on the surface of magnesium alloy . Experimental results of wettability test, electrochemical test, and immersion test revealed that SLIPS exhibited outstanding anti-corrosion and durability. More importantly, the open circuit potential (OCP) fluctuated slightly and a lower friction coefficient for SLIPS was detected in the tribo-electrochemical test, which indicates that the micro-nano-scale composite structure on SLIPS can effectively lock the lubricant oil and provide sufficient lubrication for the friction pairs.

Although MXene-based epoxy coatings have been proven to have excellent wear and corrosion resistance, their failure in tribocorrosion environments will be accelerated. Here, tung oil-based urea-formaldehyde microcapsules were in situ loaded onto Ti3C2Tx MXene nanosheets (MLU) and incorporated into an epoxy coating (MLU@EP). The tribological properties of MLU@EP under tribocorrosion conditions were evaluated, and the related protective mechanisms were thoroughly investigated by the combined use of experiments, molecular dynamics simulations, and machine learning methods. As a result, MLU@EP with a pH/mechanical dual-stimulus-response exhibited significantly improved tribocorrosion resistance. The friction coefficient was reduced by 58%, while the wear rate decreased by 94% (1.6 × 10–5 mm3/N·m). Moreover, the open circuit potential remained highly stable (ΔVocp < 0.077 V) at a more positive value. SEM-EDS images and Raman spectra revealed a time-dependent evolution of the worn surface, where progressive deposition of a tung oil/MXene-based lubricating film enhanced and stabilized lubrication with increasing friction cycles. Machine learning further decoupled the effects of friction frequency, load, and filler content over the wear cycle, confirming that the film enabled rapid lubrication and progressively improved over the wear cycle. In addition to the formation and cyclic evolution of the lubricating film, enhanced deformation resistance and effective barrier effects also contributed to the enhanced tribocorrosion performance. This work established a novel intelligent coating design methodology that enhanced tribocorrosion resistance and offers guidance for applications under complex operating conditions.

This study aimed to investigate the enhancement of the corrosion and tribocorrosion performance of AZ31B magnesium (Mg) alloys after plasma electrolytic oxidization (PEO) treatment using pullulan as an electrolyte additive . The effects of different concentrations of pullulan in the electrolyte solutions on the mechanical and corrosion-resistance properties of the PEO coatings were investigated. The microstructures and chemical compositions of the coatings were investigated via scanning electron microscopy, energy dispersive spectrum, and X-ray diffraction. The corrosion resistance of the samples in simulated body fluid was evaluated via potentiodynamic polarization and electrochemical impedance spectroscopy . The tribocorrosion performance was determined by simultaneously recording the change in the friction coefficient and the open circuit potential over time during sliding experiments. The results indicated that the addition of pullulan to the silicate-based electrolyte solutions resulted in an increase in the unit-area adsorptive capacity of the negative ions at the anode/electrolyte interface, which enhanced the compactness of the PEO coating. The PEO coating produced in electrolyte solution containing 1.0 g/L pullulan exhibited the greatest thickness (50 μm), the lowest surface roughness (1.25 μm), the highest corrosion resistance, and the best anti-tribocorrosion performance, all of which corroborated the potential application of PEO-coated Mg alloys as biological implants .

A corrosion and wear resistant coating was developed on the surface of titanium alloy using micro-arc oxidation (MAO) technology with addition of lignin sulfonate (SLS) as an additive in electrolytes containing 15 g/L of Na 2 SiO 3 ·9H 2 O and 10 g/L of Na 3 PO 4 ·12H 2 O. The effects of concentration of SLS on the surface morphology, microstructure, and corrosion-wear performance of the MAO coatings were systematically investigated. Wetting properties and mechanical characteristics of MAO coatings were determined by contact angle measurements, microhardness testing, and bonding strength assessments. The corrosion resistance of the MAO coating in artificial saliva media was assessed through electrochemical testing, while its tribological and corrosion-wear performance was evaluated via dry friction tests and corrosion-wear tests, respectively. Experimental results indicate that the incorporation of lignin sulfonate as the electrolyte additive enhances pore filling within the coating matrix while improving both mechanical properties and corrosion resistance. Notably, MAO coatings with a concentration of 1 g/L exhibited superior mechanical properties; furthermore, their corrosion current density decreased by one to three orders of magnitude compared to that of the TC4 substrate.
