“…However, the corrosion resistance of magnesium and magnesium alloys is extremely poor, severely restricting their further development [3,4]. In order to expand the application of magnesium alloy and improve its corrosion resistance, the corrosion mechanism and surface protection of magnesium alloy materials have been studied extensively by domestic and foreign scholars [5][6][7][8][9]. Through surface modification and the coating on the surface of magnesium alloy, the defects of the corrosion resistance of magnesium alloys can be improved economically and effectively.…”

Many surface treatment methods are used to improve the corrosion resistance of magnesium alloys. LDH (layered double hydroxides) conversion coatings are currently found in the most environmentally friendly and pollution-free coatings of magnesium alloy. In this study, the CO2 pressurization method was applied to the preparation of LDH coating on magnesium alloy for the first time. The effect of CO2 pressurization on the formation and corrosion resistance of LDH coating on AZ91D alloy was investigated. The hardness and adhesion were significantly higher on LDH coating in the case of CO2 pressurization than it is in atmospheric pressure. The surface and cross-sectional morphologies show that LDH coating is more compact in the case of CO2 pressurization than with atmospheric pressure. The results of the polarization curve, hydrogen evolution, and immersion tests indicate that the corrosion resistance of the LDH coating prepared by the CO2 pressurization method was significantly improved.

“…The OCP value of untreated Mg alloy was −1.58 V. The E OCP values of C-LDH, CV-LDH, and CV-LDH-MXene were higher than those of untreated Mg alloy, which were −0.83, −0.77, and −0.36 V, respectively. Generally, the higher the OCP of the sample, the lower the tendency to participate in the electrochemical corrosion reaction . The results of OCP confirm the enhancement of the two-dimensional nanomaterial MXene.…”

nanomaterials have proven that potential applications in protecting metals from corrosion and wear. However, it remains a challenge in easy agglomeration and complex functionalization of 2D nanosheets in nanocomposite coatings. Herein, Co-doped MgAl-V 2 O 7 4− layered double hydroxide (LDH) with transition metal carbide (Mo 2 CT x ) nanosheet composites (CV-LDH-MXene) was synthesized by using a dopingelectrostatic synergistic assembly strategy. After layer-by-layer assembly, nanosheet composite coatings had thicknesses of −6.9 μm. The corrosion results show that the incorporation of the CV-LDH-MXene nanocomposite coating can increase impedance at 10 −2 Hz by 1 order of magnitude compared to pure LDH coating and decrease the corrosion current density by ∼30-fold. Furthermore, the friction results claimed that the CV-LDH-MXene nanosheet composites could make the coefficient of friction maintain at 0.09 after the running-in period, which displayed excellent relatively stable and anti-wear properties. These phenomena confirmed that there existed a synergistic effect of V 2 O 7 4− intercalation and layer-assembled Mo 2 CT x MXene, which achieved stable anti-corrosion and wear characteristics. This investigation proved a substantial significance for the creation of LDH and MXene nanosheets and a giant step forward in the application of anti-corrosion and anti-wear. In particular, we promote the application of nautical instruments, underwater weapons, and seawater batteries in the shipbuilding industry and marine engineering.

“…The corrosion problem, which is regarded as the main difficult problem in the application, because of the chemically active nature of magnesium, is prone to electrochemical corrosion (Pan et al , 2017; Huang and Yang, 2020; Gao et al , 2018). Therefore, compared to improving the overall performance of the magnesium alloy material, constructing a corrosion resistant surface coating on the surface of the material is an effective and economical method (Guo et al , 2019).…”

Purpose This paper aims to research the effect of different concentrations for Nd(NO3)3 and Ce(NO3)3 on the microstructures and corrosion resistance of Ni-W-P composite coatings through electroless plating method. Design/methodology/approach Scanning electron microscope, attached energy dispersive spectroscopy system and X-ray diffraction were used in this work. Meanwhile, the immersion test and electrochemical tests were used to characterize the corrosion behavior of the coating. Findings The coatings prepared at 1.00 g·L−1 Nd(NO3)3 exhibit a dense structure and high phosphorus content (12.38 wt.%). In addition, compared to the addition of Ce(NO3)3, when Nd(NO3)3 was introduced at a concentration of 1.00 g·L−1, the minimum corrosion rate of the coating was 1.209 g·m−2·h−1, with a noble Ecorr (−0.29 V) and lower Icorr (8.29 × 10−4 A·cm−2). Originality/value The effects of rare earths on the deposition and corrosion resistance mechanisms of Ni-W-P composite coatings were explored, with the rare earth elements promoting the deposition of nickel and tungsten atoms. Simultaneously, the amorphization of the coating increases, which excellently enhances the corrosion resistance of the coating.
