“…135 Therefore, instead of repairing surface hydrophobicity or bulk integrity, the self-healing regime in this case takes effect by the autonomous inhibition of corrosion reactions. Besides direct doping, [136][137][138] corrosion inhibitors were more frequently stored in micro/nanocapsules [139][140][141][142][143] and fibers 144 and then mixed in coating matrix for more efficient or pH-responsive releases. A list of excellent articles can be referred to for the reviews of inhibitor-containing self-healing anticorrosive coatings.…”

Due to their superior water-repelling effects, superhydrophobic surfaces have received increasing attention as a promising solution to corrosion of metallic materials. The present article introduces the fundamental theories behind superhydrophobicity followed by a comprehensive review of the recent progresses of this rapidly growing field over the past 5 years. A critical discussion over anticorrosion mechanisms of superhydrophobic surfaces is also provided. For many realistic applications, future efforts are pressingly demanded to prolong the corrosion resistance of these superhydrophobic surfaces. To this end, several important strategies and examples in designing stable, selfhealable, or inhibitor-loaded superhydrophobic surfaces are discussed.

“…Such an approach would allow for using the encapsulation of functional agents for self-healing to develop coatings with self-healing capabilities [37]. For example, combined uses of different carriers/structures (e.g., capsules, hollow-particles, mesoporous particles, layered-clays or tubular reservoirs) containing healing or functional species which are sensitive to different stimuli and loadings, and hence, respond to different kinetics of release, would allow for the development smart coatings with multi-functionalities, notably, self-healing, antifouling and super-hydrophobic coatings [38].…”

Abstract. The aim of this paper is to present a critical analysis of existing methodologies, approaches and strategies used to develop materials systems and coatings for uses in extreme environments. The extreme or harsh conditions encompass a large variety of in-service forms such as: extreme temperatures, abrasion, corrosion, impact and radiation that can exist in various applications such as those associated with aerospace and aeronautical engineering, land and marine transport, manufacturing machinery, and even microelectronics products. This article describes how working environment and required service performance of a particular part or structure could affect the choice of materials and surfaces to which it is composed. In addition, the paper explains the relevance that abusive working environments have for industry, especially relating to their costs, being followed by an overview of surface deposition approaches that are currently popularly used to improve performance of mechanical devices that need to combat adverse conditions. Finally, a material system and three kinds of protective coatings that could be used in applications in extreme conditions are described. The critical review is an outcome of the strategic review from the EU H2020 SUPERMAT project which deals with materials and manufacture for the products/structural parts used in extreme conditions. Keywords: extreme environment / material system / surface treatment / coating / economic impacts / case study Extreme environment and material-related issuesA harsh environment could be any environment that impedes the operation of a device/system. Many types of the conditions could be considered to be harsh, such as: extreme pressure/temperature, shock, vibration, chemical reactivity, radiation, corrosion and humidity, ranging from the applications in, such as alloy production, component manufacture, transport and biomedical implants [1] while the energy sector faces additional harsh environment such as that in various power plants [2], some of such examples being listed below: -Transport: Automobiles and airplanes that are operated in extreme conditions, being exampled by engines components and high-friction paired parts; -Energy: The devices/pipelines/components used for energy conversions, transports and storages, which faces high-temperature, various kinds of mediums and nuclear/chemical reactions, and suffer from corrosion and fatigue failures; -Manufacturing: Tools (e.g. cutting tools, dies and moulds, welding tools, high-temperature nozzles, etc.) used in manufacturing processes;

“…The encapsulation of the inhibitor into the containers (AA-coat-CeMo-MBT) instead of its addition into the coating (AA-coat-MBT) probably impair the coating coherence to a lesser degree resulting in improved corrosion protection properties. Furthermore, it is assumed that the release of the inhibitor from the containers after the onset of corrosion results, in the case of AA 2024-T3, in the dissolution inhibition of the adjacent anodic materials surrounding the Al (Fe, Mn, Mg/Si) ( Table 1) intermetallic particles through the formation of stable complexes between the metals and the thiol groups [35,36]. Except for the MBT inhibitor, the shell of the CeMo containers acts itself as corrosion inhibitor due to its dissolution to MoO 4 À2 and cerium ions in corrosive environment.…”

-The current study investigates the effect of nanocontainers incorporation into sol-gel coatings for the protection improvement of aluminium alloys 2024-T3 against corrosion. The nanocontainers were synthesized via a combination of radical polymerization process and sol-gel technique. They consist of cerium and molybdenum oxides and loaded with the anodic corrosion inhibitor 2-mercaptobenzothiazole (MBT). The preparation of the coating matrix was accomplished using (3-glycidoxypropyl)trimethoxysilane as precursor. These organic modified silicate based sol-gel films were evaluated for their corrosion behaviour as well as nanomechanical properties using electrochemical and nanoindentation techniques, respectively. The results reveal that the presence of loaded nanocontainers improved the corrosion protection of the coatings; outcome that can be attributed to either the increase coherence of the coating or the simultaneously inhibition action of cerium and molybdate ions together with the corrosion inhibitor MBT. Moreover, the addition of nanocontainers empty or loaded with inhibitor amount strengthens (increase of wear resistance) the coating and decreases the coefficient of friction.
