“…In order to extend the possible applications of metals and protect them against corrosion, a wide range of coatings have been applied in the past. Among them, hybrid organic-inorganic sol-gel silica coatings seem to be the most promising ones due to high versatility, simple processability, and the possibility to tailor their characteristics, ranging from those typical of polymers, like flexibility and softness, to those typical of ceramics, like hardness, abrasion resistance, and brittleness [2]. Sol-gel processing temperature is low, frequently close to room temperature, allowing to avoid thermal volatilization and/or degradation of entrapped species, e.g., organic inhibitors or organic functionalization [3].…”

We developed hybrid organic–inorganic sol–gel silica coatings with good durability in harsh environment (high temperatures, high vapor velocities) and with slightly hydrophobic behavior, sufficient to promote dropwise condensation (DWC) of pure steam. DWC is a very promising mechanism in new trends of thermal management and power generation systems to enhance the heat transfer during condensation as compared to film-wise condensation (FWC). The sol–gel coatings have been prepared from methyl triethoxy silane (MTES) and tetraethyl-orthosilicate (TEOS) and deposited on an aluminum substrate. The coatings were optimized in terms of precursor ratio and annealing temperature highlighting potentials and limits of such mixtures. A comprehensive surface characterization before and after saturated steam condensation tests has been performed and related to the thermal measurements for evaluating the heat transfer augmentation as compared to FWC obtained on untreated aluminum surfaces. The results showed that the developed hybrid organic-inorganic sol–gel silica coatings are promising DWC promoters.

“…However, at present, they are almost completely banned due to the high toxicity and environmental effects associated with their use (Directive of the European Parliament and of the council on end-of life vehicles, 2000). In this regard, a search for alternative variants is actively conducted to ensure high protective properties of anticorrosion paint coatings (Hihara, 2018;Radwan et al, 2018;Tiwari, 2018). The conclusion that one of the ways to solve the posed problem is the use of complex oxides of various metals, which are non-toxic entities as anti-corrosive pigments should be taken as a result of this search (Stepin et al, 2001;Sørensen et al, 2009;Kalendova et al, 2006).…”

Purpose The purpose of this paper is to search for toxic anticorrosive pigments’ substitute in protective coatings is one of the important tasks that the specialists in the field of steel corrosion face. Design/methodology/approach One of the ways to solve the problem of metal corrosion is to use complex oxides as pigments, which are characterized as low-toxic compounds and possess the ability to inhibit corrosion. Findings In the production of ferrites, it is possible to use production waste as raw material, and that makes it possible to reduce the price of the resulting product and solve environmental problems simultaneously. Originality/value Permanent growth of world production is accompanied by the increasing environment corrosiveness, associated with the intensification of air, water basin and soil pollution by industrial waste. This, as well as the continuously increasing operated metal stock, has recently made the tendency of metals’ total loss from corrosion steadily increasing. All of this points to the importance of studying corrosion processes and the systematic and effective fight against metal corrosion.

During transportation, long-term storage and operation metal products are exposed to atmospheric corrosion that leads to billions of losses every year. The urgency of the problem being investigated is due to the fact that export of metal products is mainly carried out by sea through regions with humid tropical climate. The search for new packaging materials is a significant trend in corrosion control. The research of effective corrosion inhibitors that are capable to protect all kinds of metals, such as steel, zinc, copper, aluminum, is actually carried out, as well as the process of development of getting the packaging materials containing the corrosion inhibitors. The purpose of this paper was a research of anticorrosive properties of experimental packaging papers under increased humidity and in the presence of chloride of sodium. In this paper the test conditions which, correspond to the handling conditions of steel products through the zones with tropical climate, were simulated. The studies research found out that the experimental patented corrosion inhibitors do not take protective effect on galvanized steel. The generated corrosion products are incoherent, weakly coupled with metal and easily fall off (crumble), that results in metal loss.
