“…Then, the anticorrosion performance of the coating decreases sharply after cracking . This is mainly because of the internal stress and defects in the curing process of epoxy resin . By enhancing the toughness of epoxy resin coating, the internal stress after curing can be reduced, to avoid or delay the occurrence of cracking .…”

“…48 This is mainly because of the internal stress and defects in the curing process of epoxy resin. 56 By enhancing the toughness of epoxy resin coating, the internal stress after curing can be reduced, to avoid or delay the occurrence of cracking. 57 The initiation of cracks provides channels for the corrosive solution to reach the surface of the steel, making the occurrence of corrosion, which indicates the failure of the coating.…”

The Improved Antiwear and Anticorrosion Properties of Epoxy Resin with Metal–Organic Framework ZIF-8 Containing Lubrication Oil

Zeolitic imidazolate framework-8 (ZIF-8) was fabricated as a lubrication container to encapsulate lubrication oil, which was added to epoxy resin (EP) as a filler to get the self-lubricating ZIF-8/EP composites coating. The antiwear and anticorrosion peculiarities of EP can be significantly improved by the encapsulation method. The antiwear peculiarities of EP were evaluated by the macroscopic ball-disk friction tests with the 9Cr18 steel ball as the counterface material. The result demonstrates that the coefficient of friction (COF) and wear rate of the self-lubricating ZIF-8/EP composites were reduced by 82.1% and 93.5% compared with that of the pure EP, respectively. Importantly, the ZIF-8/ EP composite shows anticorrosion performance in the artificial seawater (ASW). The constant phase element and effective capacitance of the coating containing ZIF-8 fillers are lower than that of the non-containing coating. In addition, the diameter of the capacitive arc and the impedance modulus of the coating containing ZIF-8 + YR1800 are higher than those of the coating non-containing, which proved that the corrosion resistance of the EP is improved by the ZIF-8 + YR1800.

“…Since natural weathering is strongly influenced by solar radiation, a laboratory ultraviolet B-rays (UVB) radiation test is also included in the investigation. [13][14][15][16][17] The aggressiveness, acceleration, and degradation morphology of the accelerated test investigated in this work are assessed by coupling the EIS results with the visual inspection of the aged samples. EIS is a nondestructive technique capable of evaluating the corrosion protection properties, [18][19][20][21] and it is recognized to provide insights into the water uptake [22] and the electrochemical activity of the metal/polymer interface.…”

Since testing organic coatings under natural conditions is a time‐consuming process, accelerated methods are needed to produce results in less time. A simulated environment cannot fully reproduce actual operating conditions, so it is important to investigate the correlation between accelerated and natural aging test results. In this article, the natural aging of painted steel, aluminum, and hot‐dip galvanized steel is studied for 1 year under continental climate conditions. The environmental parameters responsible for the change of the protective system in a continental urban environment were monitored: time of wetness, ultraviolet radiation, and temperature. The extent of deterioration is compared with similar samples weathered by accelerated testing using electrochemical impedance spectroscopy, differential scanning calorimetry, and gloss measurements. Neutral salt spray chamber, prohesion test, immersion in a quiescent salt solution, and ultraviolet B‐rays (UVB) exposure test are considered. The results of the accelerated cabinet tests are discussed, and the effect is evaluated for the various coated metals. This study highlights the major problems encountered in building a model to predict durability in such a critical area as the durability of organic coatings for metal structures.

“…On the other hand, Whirling arm rain erosion tests and droplet rain erosion tests were performed by different researchers on the coating systems subjected to various speeds and impact angles to understand the coating behaviour. if the coatings peel off under these tests it is considered that the composites shall not be used without coatings during the rainy season [33][34][35].…”

In the present study, glass-epoxy composites were used as a substrate to study the performance of modified polyurethane coating. Two-layer coating (180-200 µm) wherein the epoxy primer as the first coat and polyurethane as the top coat was applied using an air-assisted spray gun to increase the service life of the composite. The analysis of coating was performed using gloss, contact angle, FTIR, TGA, tensile test and SEM. The bonding strength between coating and substrate was evaluated by cross-hatch cut, 180 deg peel strength and pull-off adhesion tests. Scratch, Taber abrasion and Pin-on-disc tests were also performed to evaluate the wear resistance. In addition, a rain erosion test was performed to check the stability of the coating. From the above tests, it is concluded that the applied coating well adhered to the composite substrate. The data generated from different tests can be used to estimate the service life of polymer composites and coatings.
