“…The oxide film at the three-phase wire will be destroyed by zinc vapor reduction and interface reaction products, so the substrate at the three-phase wire will be cleaner and the interface reaction intensity will be more intense. Fe-Zn is an intermetallic compound formed by a solution reaction without the formation of new chemical bonds between the compounds [24]. At the same time, because the Sb element has less surface tension, the wettability of zinc liquid can be improved.…”

The wetting behavior of molten Zn and Zn-Sb alloy and X80 steel in a high vacuum environment was studied by the modified sessile drop method. The wetting morphology and interface structure were analyzed by scanning electron microscope and energy dispersive spectrometer. The results show when the content of Sb in Zn-Sb alloy increases from 0.0 wt. % to 1.0 wt. %, the initial contact angle between the droplet and the substrate decreases from 102.8° to 82.5°, and the equilibrium contact angle also decreases from 57.4° to 41.4°. Sb element in the Zn-Sb alloy can reduce the contact angle and improve the wettability due to its smaller surface tension. The spreading process of Zn-Sb alloys on X80 steel can be divided into rapid adsorption, reaction control, steady-state equilibrium stages, and Zn-Sb alloys with different mass fractions have the same spreading kinetics. The volatilized Zn element in the Zn-Sb alloy will reduce the oxide film on the surface of the substrate, making it easier for the Zn-Sb droplet to wet the steel plate and induce the formation of a precursor film. The formation mechanism of the precursor film is the subcutaneous penetration mechanism.

“…In addition, they also tested the modified magnetite in different bacterial and fungal strains and found that the modified magnetite had excellent antibacterial properties. There is no doubt that the gallic acid-modified magnetite has a denser structure, a more dispersed distribution and a bacterial inhibition function, which can produce more excellent corrosion resistance for the coating (Li et al , 2022b). In addition, because magnetite can be adsorbed on a certain side by the magnet (Figure 6), thereby greatly improving the corrosion resistance of a certain part of the coating, gallic acid-modified magnetite can also produce some additional functional potential.…”

Purpose Gallic acid is a substance that is widely found in nature. Initially, it was only used as a corrosion inhibitor to retard the rate of corrosion of metals. In recent years, with intensive research by scholars, the modification of coatings containing gallic acid has become a hot topic in the field of metal protection. This study aims to summarize the various preparation methods of gallic acid and its research progress in corrosion inhibitors and coatings, as well as related studies using quantum chemical methods to assess the predicted corrosion inhibition effects and to systematically describe the prospects and current status of gallic acid applications in the field of metal corrosion inhibition and protection. Design/methodology/approach First, the various methods of preparation of gallic acid in industry are understood. Second, the corrosion inhibition principles and research progress of gallic acid as a metal corrosion inhibitor are presented. Then, the corrosion inhibition principles and research progress of gallic acid involved in the synthesis and modification of various rust conversion coatings, nano-coatings and organic resin coatings are described. After that, studies related to the evaluation and prediction of gallic acid corrosion inhibition on metals by quantum chemical methods are presented. Finally, new research ideas on gallic acid in the field of corrosion inhibition and protection of metals are summarized. Findings Gallic acid can be used as a corrosion inhibitor or coating in metal protection. Research limitations/implications There is a lack of research on the synergistic improvement of gallic acid and other substances. Practical implications The specific application of gallic acid in the field of metal protection was summarized, and the future research focus was put forward. Originality/value To the best of the authors’ knowledge, this paper systematically expounds on the research progress of gallic acid in the field of metal protection for the first time and provides new ideas and directions for future research.

“…The alloy coating can also form new corrosion products to provide a supplementary self-healing effect [8,9]. Si can effectively reduce the thickness of the Fe-Al alloy layer [17,18]. However, Si particles also precipitate in the coating, which aggravates the corrosion of the coating to some extent [16].…”

The effect of Mg addition on the microstructure and sacrificial anode protection performance of a hot-dip Al-5Zn-4Si-xMg coating was studied by scanning electron microscopy (SEM-EDS), an X-ray diffractometer, and an electrochemical workstation. The results showed that Al-Zn-Si alloy was composed of an Al-rich phase and a Zn-rich phase. The MgZn2 phase appears after Mg addition. When the addition of Mg increased to 0.15 wt.%, the Mg2Si phase began to appear in the alloy. The hot-dip Al-5Zn-4Si-xMg coating consisted of Si particles, an Al-rich phase and a Zn-rich phase. When the Mg content increased to 0.15 wt.%, the Mg2Si phase and Al + Zn + MgZn2 eutectoid phase began to appear in the coating. In the full immersion corrosion test of the hot-dip Al-5Zn-4Si-xMg coating, the order of corrosion resistance was 0.15% Mg coating > 0.2% Mg coating > 0.05% Mg coating > 0 Mg coating. In the corrosion process of the hot-dip Al-5Zn-4Si-0.15Mg coating, with the increase in immersion, the self-corrosion current of the coating decreased, and the sacrificial protection performance was the best.
