“…The barrier properties of a coating can slow down the diffusion rate of the aggressive electrolyte towards the metal substrate. However, the presence of local defects or damage on the coating surface may allow an easier penetration of the aggressive species towards the metal interface, strongly limiting its durability [4]. Consequently, the synergistic integration of the barrier action with active protection-e.g., through the addition of green inhibitors-represents an effective and reliable potential development strategy to obtain longtime durable coatings [5,6].…”

Research activity concerning nanoporous zeolites has grown considerably in recent decades. The structural porosity of zeolites provides versatile functional properties such as molecular selectivity, ion and molecule storage capacity, high surface area, and pore volume which combined with excellent thermal and chemical stability can extend its application fields in several industrial sectors. In such a context, anti-corrosion zeolite coatings are an emerging technology able to offer a reliable high performing and environmental friendly alternative to conventional chromate-based protective coatings. In this article, a focused overview on anti-corrosion performances of sol-gel composite zeolite coatings is provided. The topic of this review is addressed to assess the barrier and self-healing properties of composite zeolite coating. Based on results available in the literature, a property–structure relationship of this class of composites is proposed summarizing, furthermore, the competing anti-corrosion active and passive protective mechanisms involved during coating degradation. Eventually, a brief summary and a future trend evaluation is also reported.

In this study, we demonstrated a facile approach for the synthesis of nanocontainers using the encapsulation of a 2‐mercaptobenzothiazole (MBT) inhibitor; these nanocontainers were capable of responsively releasing a corrosion inhibitor and of self‐healing performances. The anticorrosive performance of the CeO2 nanocontainers was investigated with electrochemical impedance spectroscopy (EIS) measurement in a saline electrolyte via the incorporation of different weight percentages (0.5, 1, and 2 wt %) of synthesized nanocontainer in epoxy (EP) resin. The EIS results show that the loading of 1 wt % CeO2 nanocontainer containing MBT inhibitor in the epoxy (EP) coating [EP/NC MBT–CeO2 (1%)] provided the highest Rcoat, the lowest constant phase element of coating, and the optimum release of MBT at different operating pHs. The highest coating resistance Rcoat values of this coating (7.81 × 107 Ω cm2) were about 12 and 8573 times greater than those considered for EP–CeO2 and EP coatings, respectively. Different releases of the MBT inhibitor were detected at various pHs. We found that the coating operating in acidic media exhibited a better self‐healing performance. © 2018 Wiley Periodicals, Inc.

“…In a typical procedure of preparing a coating, a certain amount of the coating paint was dropped on the surface of a freshly polished steel substrate. The brush of a wire bar coater (ZBQ 100/200/300/400, Pusheng Testing Instrument Co. Ltd. (Shanghai, China)) uniformly spread the paint over the substrate at a constant sliding speed (~150 mm/s) to make a uniform coating [21,22]. The wet film thickness of the coating was 400 µm.…”

Inorganic–organic composite coatings with fluoroethylene vinyl ether (FEVE) resin as polymer matrix and sodium iron titanate (NFTO) whiskers with different aspect ratios as reinforcement filler are prepared by the liquid-phase blending method. The influence of aspect ratio and content of NFTO whiskers on the morphology, and the mechanical and tribological performances, of NFTO-reinforced FEVE composite coatings are investigated. The addition of NFTO whiskers can obviously enhance the mechanical and wear resistance performances of the composite coatings and reduce the friction coefficient. The worn surface and wear debris of the composite coatings are studied with scanning electron microscopy (SEM) to reveal the friction-reducing and wear resistance mechanisms. The composite coating filled with ~10 wt.% NFTO whiskers has the best wear resistance performance, since the monodispersed hard whisker can carry the load applied on the sliding surface and reduce the adhesive wear of the polymer matrix. Among the three types of NFTO whiskers, the whiskers with a medium aspect ratio show the best reinforcement effect since they provide the optimum mechanical support to the polymer matrix and cannot be pulled out from the matrix easily.
