| Steel is widely applied in various fields due to its outstanding mechanical properties. However, the corrosion of steel has been a puzzling problem for a long time. Organic coatings are commonly used for protecting steel from corrosion effects due to their excellent adhesion, simple process of preparation, and superior long-term corrosion resistance. The types of materials, the orientation of fillers, and methods of modification in organic coatings have a certain impact on the corrosion and tribological performance of the coatings. The work aims to briefly introduce the research progress on anti-corrosion and tribological performance of organic coatings on steel in recent years. Firstly, four methods of improving the corrosion protection performance of organic coatings were introduced in sequence, including formation of physical barriers, cathodic protection at the expense of the anode, self-healing technology and superhydrophobic technology. The basic principles of each method were elaborated, and the corrosion protection performance of organic coatings on steel prepared by various methods was compared. Then, the problems of organic coatings prepared by the four methods were analyzed. The dispersion and orientation of two-dimensional materials in organic coatings greatly affected the barrier properties. How to achieve good compatibility and parallel distribution of two-dimensional materials in coatings was the key to improving the corrosion resistance of coatings. The method of cathodic protection at the expense of the anode required a large amount of sacrificial materials to form a stable conductive network, which could lead to an increase in the porosity of coatings and a decrease in the adhesion between substrates and coatings. How to reduce the number of sacrificial materials added to coatings while ensuring the stability of electrical connections was a problem required to be considered in the current preparation of such coatings. The self-healing coatings should improve the mechanical properties on condition that the anti-corrosion performance and self-healing rate were not affected. When introducing corrosion inhibitors into self-healing coatings, it was necessary to consider the negative impact that corrosion inhibitors brought. Preparing self-healing coatings that were environmentally friendly and had long-term and stable release of corrosion inhibitors was of great significance. Under the premise of not reducing hydrophobicity, the superhydrophobic coatings were required to improve the robustness and durability of rough surfaces, as well as the chemical stability of substances with low surface energy. At the same time, the approaches which could be used for solving these problems above were discussed as well. Subsequently, the effect of different fillers on the tribological performance of organic coatings on steel was mainly explored from the perspective of doped fillers. Three strategies to improve the tribological performance of organic coatings were proposed, including the synergistic effect of lubricating phases and reinforcing phases, the synergistic effect of soft phases and hard phases and adding self-lubricating microcapsules. At present, organic coatings on steel have achieved significant results in the improvement of anti-corrosion and tribological performance. However, there are still many challenges in current research work of organic coatings on steel. Finally, the challenges which organic coatings on steel faced are summarized, and the development direction of organic coatings on steel is prospected. |
