“…Halloysite nanotubes and boehmite nanoparticles are employed as reservoirs for corrosion-inhibiting compounds [57][58][59]. Cerium cations [58,[60][61][62], 8-hydroxyquinoline [48,57], benzotriazole [45,48,49,63,64], mercaptobenzimidazole (MBI) [63], dicyclopentadiene (DCPD), alkoxysilanes [65], silyl ester [24], linseed oil [37,44,66], hexamethylene diisocyanate (HDI) [40], triethanolamine (TEA) [41], monomers and catalysts for ROMP [67], magnesium ions [68], chromium(III) and cerium(IV) oxides [34] and cerium(III) chloride [60,69] are used as corrosion inhibitors. The action mechanisms connected with the particular compounds are presented in Table 1.…”

Nonmetallic (based on polymers or oxides) and metallic protective coatings are used to protect metal products against the harmful action of the corrosion environment. In recent years, self-healing coatings have been the subject of increasing interest. The ability of such coatings to self-repair local damage caused by external factors is a major factor contributing to their attractiveness. Polymer layers, silica-organic layers, conversion layers, metallic layers and ceramic layers, to mention but a few, are used as self-healing coatings. This paper presents the main kinds of self-healing coatings and explains their selfhealing mechanisms.

“…This work demonstrated that the silyl esters were able not only to wet the damaged surface but also the cut edge of the coating, avoiding further leakage of the inhibitor from the coating, Figure 6.21. Latnikova et al [88] used microcapsules loaded with alkoxysilanes in PU. The applied coating was then tested in 0.1 M NaCl solution for 6 h. Accordingly, alkoxysilanes possessing a long hydrophobic tail were found to display better corrosion resistance than those without a tail, as a result of the water-repelling properties of the tails [88].…”

For decades, iron and steel have been two of the most important materials in our daily lives due to their good mechanical properties, availability and relatively reasonable cost. However, iron does not exist in nature as iron, but as a compound such as iron oxide. In order to get a usable material, these compounds must be refined and processed from their natural state. The conversion process (reduction, eq. 6.1) of iron from iron ore is undertaken by heating, therefore providing energy, with carbon under careful control, in order to prevent the reverse reaction. 2Fe 2 O 3 + 3C → 4Fe + 3CO 2 (6.1)According to the second law of thermodynamics [1, 2], there is a strong tendency for the system to move from order to disorder: its energy tends to be transformed from high energy states into lower levels energy states available, in order to reach the state of complete randomness and be unavailable for further work. Corrosion occurs due to this tendency of metals to recombine with components of the environment to reach its low energy state. In the case of iron, the metal tends to be oxidized into a reddish oxide, commonly known as rust, leading to a gradual destruction or deterioration of the metal [3-7]. All metals, with a few exceptions such as gold and silver, show this natural tendency to return to their lower energy state to form oxide and hydrate and therefore are prone to corrosion. Corrosion degradation is one of the main reasons for large industrial losses. One of the most suitable methods to protect metal for the external environment is the application of coatings on the metal's surface. Coatings are designed to protect the metal by physically isolating and preventing the diffusion of aggressive species towards the metal surface. However, coatings are prone to degrade, either because of the long exposure time -processes commonly known as weathering and ageing (e.g. moisture, UV radiation, thermo-oxidation, etc.) -or mechanical factors (e.g. damage due to impacts, scratches, defects, etc.). These chemical and mechanical degradation processes will eventually lead to the formation of microcracks and premature failure of the coating system. When the coating fails, the corrosion of the substrate is greatly accelerated. Repairs and maintenance of failed coatings are well-known to be both expensive and time consuming. Therefore, an active protection in addition to the time-limited passive protection is required. In order to prolong the service life of the metallic structures, scientists have developed a new class of intelligent polymeric coatings able to fully or partially regenerate their structural integrity resulting from external damage, without the help of any external Unauthenticated Download Date | 6/22/16 4:26 PM

In recent years, self-healing coatings have been the subject of increasing interest. The ability of such coatings to self-repair local damage caused by external factors is a major factor contributing to their attractiveness. Metals are extensively used in modern society in a range of applications from infrastructure to aircraft to consumer products. The protection of metals, primarily from corrosion has been an active area of materials science for many years. The aim of this review is the demonstration for recent progress achieved in the development of carrier-based self-healing coatings for the protection of metals. This review mainly covers the reports published after 2010. Two main types of carriers for corrosion inhibitors or healing agentspolymer capsules and porous composite inorganic nanoparticles-are described.
