“…Afterward, due to the alkaline environment on the cathodic area, the precipitation of cerium oxide, CeO 2 is a consequence of a further interaction with the hydroxyl groups according to the reaction 2. The precipitation of a stable and compact CeO 2 oxide significantly delays the activation and evolution corrosion phenomena, providing reliable coverage on the defective areas, thus improving the passivating action [117].…”

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.

“…According to multiple published articles, most of the nanoparticles added to the coating bath are incorporated with the deposited metal matrix on the surface of the substrate. As a result, different properties of the deposited layer become noticeable because of the added nanoparticles' physicochemical and mechanical properties [12] [13] [14].…”

The composite coating has gained wider attention due to its property to protect materials used in energy, bridges, offshore platforms, underground pipelines, and the aviation industry from corrosion and deterioration. In this work, a literature review was conducted about the processes of nanocomposite coating, the mechanisms of electrolytic co-deposition, the texture of layers, and the residual stresses. An important aspect, residual stress, was emphasized, which represents the persistent stress after removing the external force affecting a metal in the plastic region. Because it cannot be measured directly and may be determined by measuring strain and indirect methods, the sources and methods for measuring residual stresses (XRD, SEM, TEM, EDS) were described in the last section to provide a comprehensive overview. Based on the thorough analysis of the published literature, it was concluded that nanoparticles could be electrodeposited with Ni on an Al substrate using a direct current and Ni sulfamate as an electrolytic solution, and Nickel will not reside on the oxide layer covering Al, so chemical changes are needed to prepare the Al surface. In addition, texture changes with the thickness of the coated layer must be investigated.

“…The Ce based coatings are seen to alter the cathodic activity by forming some insoluble hydroxides. Although the cerium conversion coatings are less improvised than the Cr based but in recent context they are conveyed as one of the most promising environmentally friendly surface treatments for a wide range of metals [15] . The incorporation of rare earth inhibitors into the filler (mesoporous silicates) of epoxy‐based systems showed an improvement by reserving and controlling the release of the inhibitors.…”

Ordered mesoporous silica was synthesized through sol‐gel technique under hydrothermal conditions by using tetraethylorthosilicate. The template free material was obtained by calcination and the channels of ordered mesoporous silica (OMS) were successfully loaded with cerium (corrosion inhibitor). This cerium loaded material was modified with N1‐(3‐Trimethoxysilylpropyl)diethylenetriamine through grafting with surface hydroxyl group. Subsequently, the surface‐modified material was actively used as a curing agent, host for corrosion inhibitors and filler as well in epoxy‐based coatings for mild steel. The mesoporous silica material was characterized by using a combination of various analytic and spectroscopic techniques like FT‐IR, powder‐XRD, N2 sorption, solid state 29Si and 13C MAS NMR studies. The physicochemical, physicomechanical, and thermal properties of the hybrid film were analyzed through standard techniques like FT‐IR, TGA‐DTA, DMTA and FE‐SEM. The coated hybrid film on mild steel was tested for corrosion inhibition by using potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) studies. The aforementioned studies revealed the developed coating system exhibited promising corrosion protection performance which was evident from icorr (6.65 nA), Ecorr (−502.850 mV), impedance (1.2×106 Ω) and phase angle (>80°). The observed water contact angle (WCA)>90° suggesting the hydrophobic nature of the coated surface.
