“…Wide-ranging industrial applications are anticipated for several synthetic superhydrophobic, SHP, surfaces that were inspired by lotus leaves 1 . SHP surfaces are exceptionally water-repellent surfaces with a water contact angle, WCA, of more than 150° and a water sliding angle, WSA, of lower than 10° 2 , 3 .…”

In this study, we report an eco-friendly and facile process for the synthesis of biochar, BC, and a cobalt-biochar nanocomposite, Co-BC, using rice straw biomass. We constructed two superhydrophobic coatings on steel substrates using potentiostatic electrodeposition of nickel-modified biochar, Ni@BC, and nickel modified by cobalt-biochar nanocomposite, Ni@Co-BC, then, these coatings were soaked in an ethanolic stearic acid solution. Fourier transform infrared spectroscopy showed that the stearic acid-grafted Ni@BC coating, Ni@BC@SA, and the stearic acid-grafted Ni@Co-BC composite, Ni@Co-BC@SA, were well grafted on the steel surface. Scanning electron microscopy revealed that the superhydrophobic coatings have nanoscale features. Atomic force microscopy results showed that the Ni@Co-BC@SA coat had higher roughness than Ni@BC@SA, resulting in higher superhydrophobicity. The water contact angles for Ni@BC@SA and Ni@Co-BC@SA coatings were 161° and 165°, respectively, while the values of water sliding angles for both coatings were 3.0° and 1.0°, respectively. Quantitative estimation of the scale inhibition efficiency revealed that the Ni@Co-BC@SA coating exhibited greater efficiency compared to the Ni@BC@SA coating. Additionally, the Ni@Co-BC@SA coating demonstrated improved corrosion resistance, UV resistance, mechanical abrasion resistance, and chemical stability compared to the Ni@BC@SA coating. These results highlight the superior performance of the Ni@Co-BC@SA coating and its potential as a highly effective and durable superhydrophobic coating for steel substrates.

“…In order to improve the wave absorption and corrosion resistance of magnesium alloys, Ni, barium ferrite (BF) and carbonyl iron (CI) powders were coated on the magnesium matrix in the form of microwave absorbing coatings to improve the wave absorption properties 20,21 . Microarc oxidation coating (MAO) [22][23][24][25] sol-gel coating 26,27 chemical conversion coating 28,29 , hydrothermal treatment 30,31 and other surface treatment methods can improve the corrosion resistance to a certain extent. The coating prepared by the micro-arc oxidation process has good hardness, adhesion and corrosion resistance, and the process is simple, clean and environmentally friendly.…”

An organic coating of about 40 mm was sprayed on the MAO coating containing Yb2O3. The main components of the organic coating are a mixture of SiO2 and α-Fe2O3 with mass ratios of 20%, 22.5% and 25%, and three different MAO/SiO2 @ α-Fe2O3 organic composite coatings are prepared. The morphology, roughness, microstructure and chemical composition of the organic composite coating are characterized. The results show that after coating the organic composite coating, the roughness of the coating is significantly reduced, and the compactness and interlayer adhesion of the coating are significantly improved. The electrochemical test and SKPFM test of the organic composite coating were carried out. The results showed that with the increase of the mass ratio of SiO2 and α-Fe2O3, the corrosion resistance and stability of the organic composite coating increased, and the Volta potential also gradually moved up. The microwave absorbing properties of organic composite coatings were studied by vector network analyzer. The results show that the microwave absorbing properties of the coatings are positively correlated with the mass ratio of SiO2 and α-Fe2O3.
