“…Due to the reduction of VOCs, it produces the least number of VOCs during curing [ 16 , 17 , 18 ]. In recent years, WBE has become increasingly popular due to its environmentally friendly characteristics [ 19 , 20 , 21 ]. In the film formation process, water’s high surface tension will unavoidably form pores and microdefects at the surface of the coating during water evaporation.…”

Due to green development in recent years, water-borne epoxy resins (WBE) have become increasingly popular since they generate the lowest level of volatile organic compounds (VOC) during curing. However, because of the large surface tension of water, it is easy to produce voids and cracks during the curing process of the coating. An electrochemical strategy was used in this study to assess the impact of different SiO2 content on the corrosion performance of a WBE coating, in which micron spherical SiO2 particles were synthesized in a liquid phase reduction. The results showed that the synthesized micron spherical SiO2 particles were about 800 ± 50 nm in diameter and in an amorphous state. By hydrophilizing the surfaces of these SiO2 particles, uniform dispersion in an aqueous solvent and a WBE can be achieved. It is important to note that adding a small or excessive amount of SiO2 to a coating will not improve corrosion resistance and may even reduce corrosion resistance. With the appropriate modification of SiO2, corrosion resistance of composite coatings is greatly enhanced, as is the adhesion between the coatings and the metallic substrates. Because the appropriately modified SiO2 can effectively fill the pores that are formed during the curing process, a corrosive medium is less likely to react with the matrix when the medium comes into contact with the matrix. Based on their incorporation content of 3 wt.%, their corrosion resistance is the best after 16 cycles of AC-DC-AC accelerated corrosion tests.

A new type of water corrosion‐resistant coating which is similar to the “Egg inlaid egg tray” structure has been successfully prepared. Modified chitosan (MCS) and graphene oxide (GO) were cross‐linked with waterborne epoxy resin to form a unique three‐dimensional “Tray” hybrid structure, and the cross‐linking reaction was catalyzed by modified nano‐SiO2 (MSiO2) with an egg‐like morphology. The uniformly dispersed MSiO2 can provide crosslinking reaction sites and is firmly “fixed” in the composite coating, thus not only catalyzing the cross‐linking reactions with well performance, but also improving the interaction between itself and the as formed GO‐MCS structure. Consequently, with the help of “fixed catalytic in‐situ cross‐linking reactions” and synergistic effect between MSiO2 and GO‐MCS, the coating not only shows an improved corrosion resistance with a large impedance modulus at low frequency (|Z|0.01 Hz) of 1.8×106 Ω·cm2, but also possesses good thermal stability and high hydrophobicity. The protective effect of the composite coating on the substrate is more comprehensive and multiple.This article is protected by copyright. All rights reserved.

Abstract2024 aluminum alloy has high strength, processing performance, and good damage tolerance performance, but it is prone to intergranular corrosion and pitting. Therefore, the development of corrosion protective coatings is essential for the aluminum alloy. In this paper, cerium ion (Ce3+) was doped into chitosan‐modified montmorillonite (Ce‐CS‐MMT) by ion exchange method, and the corrosion protective performance of Ce‐CS‐MMT epoxy coating (Ce‐CS‐MMT/EP) was investigated. The electrochemical analysis of aluminum alloy in cerium‐containing solution showed the corrosion inhibition efficiency reached 95.52%. The result indicates the corrosion inhibition effect of cerium‐containing solution was better than pure NaCl solution and MMT solution. The corrosion study of the coating illustrates that the protection rate of Ce‐CS‐MMT/EP reached 95.82%, which was higher than that 91.83% of Ce‐MMT/EP. The result indicates the resistance of charge transfer was greater and the better shielding effect for electrolyte corrosion ions than MMT and Ce‐MMT epoxy coatings, and the corrosion protective performance was excellent.
