Summary: Organic coatings are widely used to prevent corrosion of metals, but they are prone to defects and damages. Developing smart coatings that can detect corrosion and repair themselves is highly desirable. In this study, a corrosion-sensing and self-healing coating containing pH-sensitive microcontainers was designed. The coating showed excellent corrosion protection performance and could accurately report corrosion sites via coloration.

Summary: This study aims to improve the tribological properties of epoxy resins by combining self-lubrication and auto-healing. Linseed oil microcapsules with good thermal stability were successfully prepared and incorporated into the resin. The composite coating exhibited outstanding self-lubricating properties, reducing the coefficient of friction and wear rate. The formation of a uniform lubricating film and the release of linseed oil contributed to the improved wear resistance and prolonged the life of the coating.

Summary: This study developed a smart coating with corrosion-sensing and self-healing functions on carbon steel. The coating incorporated UF microcapsules loaded with Phen molecules, which acted as both corrosion-sensing indicators and corrosion inhibitors. When the coating was damaged, the released Phen molecules would react with Fe2+ ions from the carbon steel substrate, displaying a red chelate compound for corrosion-sensing application. The smart coating not only achieved timely corrosion sensing, but also effectively suppressed corrosion activity near coating scratches.

Summary: This study investigates the formation of cerium hydroxide and evaluates its capacity as a corrosion inhibitor on aluminum substrates. By immersing the substrate in a solution of cerium nitrate and hydrogen peroxide, the cerium particles are deposited on the surface. The morphological and chemical analysis of the coatings were performed, and the electrochemical corrosion behavior was studied. The results show that the presence of cerium particles can both inhibit and promote corrosion, depending on the immersion time and concentration.
