Design/methodology/approach This study designed an organic–inorganic hybrid inhibitor CLS by strategically integrating SiO2 nanoparticles into an L-tryptophan-modified CS matrix CL. The design rationale was to leverage a synergistic “anchor-and-fill” mechanism: the chemically modified CL acts not only as a primary corrosion-inhibiting moiety through strong chemisorption onto the steel surface but also as a dispersing agent and polymeric scaffold for the inorganic phase. The incorporated SiO2 nanoparticles, in turn, are intended to enhance the hydrophobicity (102.88° contact angle) and mechanical integrity of the formed protective film. The anti-corrosion properties of this designed composite were comprehensively evaluated for mild steel in HCl medium. Findings These analyses ultimately elucidated the corrosion inhibition mechanism of the organic/inorganic hybrid nanocomposite. The concept of this organic/inorganic hybrid inhibitor opens new directions for the development of low-concentration, high-efficiency green corrosion inhibitors, with the potential to inject new vitality into the field of metal corrosion protection.

Design/methodology/approach The nickel layer was obtained via constant current electrodeposition, and then the bayerite layer was grown in situ through hydrothermal treatment at 125 °C with different durations (3, 6, and 12 h). The microstructure and chemical composition of the Ni layer and bayerite layer were investigated by scanning electron microscope, energy dispersive spectroscopy, X-ray diffractometer and X-ray photoelectron spectroscopy. Their corrosion resistance was verified using electrochemical impedance spectroscopy and immersion tests. Findings Electrochemical tests in 3.5 Wt.% NaCl solution revealed that the Ni/Bayerite-6h coating exhibited the highest corrosion resistance, with a corrosion current density of 4.42 × 10−7A·cm−2 (three orders of magnitude lower than the Ni layer) and a polarization resistance of 513951 Ω·cm2. Long-term immersion tests showed that the Ni/Bayerite-6h coating delayed corrosive medium penetration for up to five days and can still prevent galvanic corrosion between the nickel layer and the aluminum substrate after seven days, significantly suppressing galvanic corrosion at the nickel–aluminum interface. The bayerite coating effectively isolates the pinholes and grain boundary gaps in the Ni layer and forms a dual-layer structure with it, providing a strong barrier against the intrusion of chloride ions.

Rebar corrosion in saltwater poses a serious threat to the durability of coastal and offshore infrastructure, prompting the need for natural, effective alternatives to conventional inhibitors. Design/methodology/approach The polyphenol content of the Syzygium nervosum extract was quantified at 5.6 g/L. Its chemical composition, rich in antioxidants and polyphenolic compounds, was analyzed to understand its corrosion-inhibiting characteristics. Electrochemical techniques – including potentiodynamic polarization and electrochemical impedance spectroscopy – were used to assess the extract’s performance. Additionally, weight loss tests were conducted in a simulated seawater environment to validate the extract’s protective capabilities. Findings The extract demonstrated significant corrosion-inhibiting efficiency by forming a protective layer on the steel surface. The corrosion rate of rebar was reduced to 0.0002 g/cm²·day in weight loss tests and to 0.070 mm/year as indicated by polarization curve results. These outcomes confirm the extract’s effectiveness in suppressing corrosion in marine-like conditions.

Findings SEM image illustrated that GO/EP coating rendered a significant portion of the surface remains relatively intact and smooth against corrosion. SVET tests presented interwoven uniform potential distribution and very small peak values of current density 236.8 µA/cm2, in comparison with higher current density of 947.4 µA/cm2 for carbon steel without GO/EP coating. LEIS tests indicated that impedance peak distribution coefficients (IPDC) of coating specimen was 7.2 pcs/mm2, which is smaller than that of carbon steel without coating with IPDC of 16 pcs/mm2.
