Eco-friendly Silane-Based Coating for Mitigation of Carbon Steel Corrosion in Marine Environments

Abstract

Losses from corrosion contribute roughly 3–5% of the gross domestic product of developed nations, and among the many methods used to avoid corrosion, using silane-based coatings is seen to be of the biggest importance due to their low toxicity and superior adhesive qualities. It is essential to develop an anti-corrosion coating that is efficient, economical, and eco-friendly. The corrosion resistance and durability of various silane-based coatings such as 1,2-bis(triethoxysilyl)ethane (BTSE), bis[3-(triethoxysilyl)propyl]tetrasulfide (TESPT), and vinyltrimethylsilane (VTES) for carbon steel 1018 substrates were investigated in a high-salinity environment (4.5 wt % NaCl). The corrosion resistance performance was evaluated via potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) techniques. Results revealed that the TESPT film (pH ≈ 7) has the best corrosion resistance performance on the carbon steel surface in the aggressive chloride environment, that is, 99.6%. The high corrosion resistance of the TESPT film is due to the hydrophobic nature of this silane, which leads to the formation of a stable and dense film. These results were supported by X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX) analyses.

Impact of cinnamaldehyde thiosemicarbazone on the corrosion of mild steel in an acidic medium

“…MS is commonly utilized as an industrial structure in the oil and petroleum industries for various purposes because of its outstanding mechanical properties [1,2]. However, MS tends to deteriorate when exposed to a corrosive environment due to its high oxidation potential, which favors the oxidation reaction and creates the foundation for the creation of an oxidized product deposit [3][4][5]. The resulting layer could affect for making surface modification and organic coatings, which are commonly active methods to guard metal from decay [6][7][8][9].…”

Toward Water and Oil Repellent Coating: Synthesis of Fluorinated Methacrylate-Glycidyl Methacrylate Copolymers

“…This multifaceted approach addresses fouling challenges across diverse industrial settings, offering a versatile and effective solution. Among low-surface energy materials, fluorinated-based materials (e.g., perfluoro silanes, , perfluoro acids, , and perfluoro polymers − ) are particularly favored for their enhanced oil-repelling characteristics due to their lower surface energy compared to hydrocarbons (CH > CH 2 > CH 3 > CF 2 > CF 2 H > CF 3 ). − Hare et al conducted the synthesis of films by depositing perfluorododecanoic acid (PFDoA) onto metal surfaces. The surface energy of PFDoA films was determined to be 6 mN/m 2 , the lowest among known surface energies.…”
