“…Sol-gel coatings prepared from condensation and polymerization of TEOS and MAPTS, TEOS and MTES, TMOS and MAPTS, or TMOS and MTES mixtures in three molar ratios were also reported by Criado et al [79,80]. For carbon steel, hybrid sol-gel coatings prepared from 3-(trimethoxysilyl) propyl methacrylate and bis [2-(methacryloyloxy) ethyl] phosphate via the sol-gel process [81] were applied. Generally, the recent publications, from 2013 to 2015 are following a tendency found previously [58], where the majority of the reported papers on this substrates use TEOS; GPTMS, MAPTS, and MTES.…”

Corrosion degradation of materials and metallic structures is one of the major issues that give rise to depreciation of assets, causing great financial outlays in their recovery and or prevention. Therefore, the development of active corrosion protection systems for metallic substrates is an issue of prime importance. The promising properties and wide application range of hybrid sol-gel-derived polymers have attracted significant attention over recent decades. The combination of organic polymers and inorganic materials in a single phase provides exceptional possibilities to tailor electrical, optical, anticorrosive, and mechanical properties for diverse applications. This unlimited design concept has led to the development of hybrid coatings for several applications, such as transparent plastics, glasses, and metals to prevent these substrates from permeation, mechanical abrasion, and corrosion, or even for decorative functions. Nevertheless, the development of new hybrid products requires a basic understanding of the fundamental chemistry, as well as of the parameters that influence the processing techniques, which will briefly be discussed. Additionally, this review will also summarize and discuss the most promising sol-gel coatings for corrosion protection of steel, aluminium, and their alloys conducted at an academic level.

“…Coated panels were vertically introduced in the setup into a three-electrode system described elsewhere [42][43][44]. A circular area of 7.55 cm 2 was exposed to a 3 wt% NaCl aqueous solution at 30 • C. The 3 wt% solution was chosen as it has a high corrosion rate on iron and can be easily compared to the literature [5,45,46].…”

“…AC impedance measurements were performed using a potentiostat Solartron SI 1287 and a Solartron 1255B (Massy, France) frequency response analyzer and ZPlot 2.80 (Scribner Associates Inc., Southern Pines, NC, USA) software was used to run the tests and to collect the experimental data. The impedance data were fitted with different equivalent circuits using with the simulation ZView 2.80 (Scribner Associates Inc., Southern Pines, NC, USA) equivalent circuit software [42][43][44]. The measurements were carried out over periods ranging from 1 h of exposure to 3 weeks.…”

In this study, waterborne hybrid organic-inorganic zinc rich coatings (ZRC) with different aluminum flake amounts were tested at low thickness in 3 wt% NaCl aqueous solution. Open circuit potential and impedance response evolution over time were measured experimentally to evaluate their anticorrosion properties. Microstructure of the investigated coatings and composition of the corrosion products were also determined by electron microscopy, X-ray diffraction and infrared spectroscopy, while the stability of the coatings was investigated via inductively coupled plasma optical emission spectroscopy. The results showed that the absence of aluminum flakes leads to a less stable matrix, unable to retain sufficient corrosion inhibitors, resulting in a shorter protection time. For an intermediate concentration of aluminum particles, good corrosion properties were observed. Corrosion products play an important role in the protection mechanism, with simonkolleite and hydrozincite accumulating over time, forming a protective layer on the substrate for several weeks. High amounts of aluminum also lead to the formation of corrosion products, but without providing a barrier effect, while rapidly consuming zinc, leading to rapid formula failure. These results indicate that the use of a controlled amount of aluminum flakes can significantly improve the corrosion protection capability of this type of coating.
