“…12 Wang et al 13 fabricated Ni 50 Nb 50 metallic glass coating by vacuum melting, which possessed higher transient current, shorter pit growth, and better repassivation rate than those of the crystallized sample. Wu et al 14 and Jiang et al 15 also magnetron sputtered the NiNb metallic glass coating on 316 stainless steel, and the results both concluded the reduced pitting susceptibility of coating as well as provided satisfactory passivation protection to the substrate. Based on above research and analysis, it can be expected that NiNb coating is an efficient anti-corrosion strategy for the long-term protection of Q235 steel in corrosive chloride environment.…”

In this work, Ni-based alloy coatings incorporated with Nb mass fractions of 0%, 3%, 6%, and 9% were successfully fabricated by laser cladding. The morphology, chemical composition, and phases of the obtained Nb-modified Ni-based coatings were characterized, and the effects of Nb contents on their electrochemical performance and immersion rates in 3.5 wt% NaCl solution were analyzed. The results show that the Ni-based coating with low Nb exhibits the most compact and refined microstructure, the best electrochemical passivation, and the lowest immersion corrosion rate of 3.30 × 10−3 mm/year. However, with increasing Nb content, the Laves phase is accumulated, and dendritic growth is promoted, which significantly decreases the coating passive stability and worsens the anti-corrosion performance.

“…Some metals are surrounded by highly corrosive environments that need protective coatings with thick layers to protect the metal from corrosion attacks. In such conditions, it is preferable to use glass coating, cured inorganic silicates, ceramic coating, sulfur, graphite, and carbon. , Glass and ceramic coatings can handle all environments except in hydrofluoric and caustic ones. Some limitations may restrict the use of glass and ceramics where they are brittle and sensitive to thermal shock and their mechanical strength is low.…”

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

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.

“…Despite the fact that 316 stainless steels (SS) are widely used in construction and marine industries, the remarkable electrochemical activity in the media containing aggressive environments containing chloride and uorine ions makes them susceptible to corrosion 10,34,35 . There are also studies evaluating the chloride corrosion behavior of 316-type SS in heating pipelines 36 and heat-exchanging surfaces 37 .…”

“…A commonly used material, stainless steel, is known to have high strength and durability, containing a passive chromium oxide lm on the surface; however, it corrodes over time in a saline environment due to the breakdown of the passivity 8, 9 . For better corrosion protection in a saline environment, magnetronsputtered NiNb thin lm coatings were utilized on 316 SS to form a stable Nb 2 O 5 passive lm 10 . In another study, ZrN thin lm coating by unbalanced magnetron sputtering on 304 SS increased the passivation behavior by at least 100 times relative to bare 304 SS by looking at the decrease in the corrosion current density 11 .…”

The resistance of commercial stainless steel (SS) types in harsh environments is problematic because of the breakdown of the passive chromium oxide layer. This study reports fully amorphized 316 SS microfibers using a customized multi-nozzled melt-spinning technique. Electrochemical tests in 3.5 wt.% NaCl shows a high corrosion resistance with an annual corrosion rate of less than 60 µm year–1 under ambient conditions, which increases slightly as the temperature rises to 50°C. The room temperature sample also shows a low passivation current at the level of 10–4 A cm–2 with long-term stability, and no pitting is observed for all the samples until 1.5 V. The sample polarized at 37°C shows the smallest bulk resistance (~ 1400 Ω cm2) and the largest double-layer capacitance (28.6 µF cm–2), where large amounts of salt accumulation on the surface creating a passive layer on the microfibers were detected by energy dispersive X-ray (EDX)–scanning electron microscopy. Cross-sectional investigation by EDX-scanning transmission electron microscopy corroborates the homogenous bulk composition and Fe-rich, Ni and Cr-containing amorphous oxides, both of which contribute to the enhanced corrosion and passivation properties compared to commercial SS counterparts in the literature.
