Nitrogen and sulfur codoped carbon dots (SB-CDs) were developed from sugar cane bagasse, an agro-industrial waste, evaluated as eco-friendly corrosion inhibitor for Q235B steel in HCl solution. The surface coverage of the adsorbed SB-CDs is strongly influenced by immersion time (6 72 h, both static dynamic conditions) concentration (20-200 mg/L). Maximum uniform achieved with 150 mg/L SB-CDs. At this concentration, demonstrated a high inhibition efficiency 96% after 6 h immersion, maintaining effectiveness at 94 92% under conditions, respectively, immersion. Electrochemical studies showed that polarization resistance (Rp) increased, current density (Icorr) decreased presence compared to uninhibited specimens, confirming SB-CDs' adsorption on metal surfaces. Additionally, analysis using scanning electron microscopy atomic force confirmed improved morphology fewer features, supporting formation protective film. Energy-dispersive X-ray photoelectron spectroscopy analyses further confirm layer SB-CDs, attributed interaction nitrogen-, oxygen-, sulfur-containing functional groups surface. Therefore, homogeneously entirely blocks iron chloride/oxide/hydroxide intermediates, ensuring corrosive environments.

This study explores the corrosion behavior of pure copper in simulated oilfield-produced water and evaluates inhibitory effect cetylpyridinium chloride (CPC) on microbiologically influenced (MIC). Weight loss tests, potentiodynamic polarization, pitting analyses revealed that sulfate-reducing bacteria (SRB) activity significantly accelerated corrosion, with maximum pit depth reaching 7.54 µm absence CPC—approximately 1.83 times greater than under abiotic conditions. The introduction CPC substantially reduced rates depths, depths decreasing to 2.97 µm, 1.11 1.02 at 10, 50, 80 mg/L CPC, respectively. inhibited SRB biofilm formation, metabolic activity, product accumulation, achieving an inhibition efficiency up 89% mg/L. These findings highlight CPC’s dual role as a biocide inhibitor, offering promising approach controlling MIC oilfields similar industrial environments.

In this study, we explore the effectiveness of glutamic acid as corrosion inhibitor for protecting steel rebars within a concrete pore solution contaminated with chloride (CCCPS) along its synergy galvanized coating are investigated. The study is defined in two phases: (a) examining inhibition efficiency (%IE) at various concentrations 0.25, 0.50, 0.75, and 1 g/L using combination experimental theoretical methods, (b) evaluating synergistic effect Zn present coating. first phase, electrochemical tests investigations employed. examinations consistently demonstrated that concentration g/L, maximum %IE reaches ∼ 80 %. Langmuir adsorption isotherm fitting effectively describes relationship between coverage percentage. Thermodynamic data indicate these inhibitors on surface involves both physical chemical adsorptions ΔG°ads (standard free energy adsorption) around –23.5 kJ/mol. Moreover, activation rebar increases from 55.8 kJ/mol blank CCCPS to 78.3 inhibited CCCPS. Molecular dynamics simulations validate binding molecules steel, primarily through nitrogen atoms orientation towards d-orbitals substrate. second carbon underwent hot-dip galvanization, resulting thickness approximately 36 µm. optimum (0.75 g/L) was investigated comparison behavior three samples: bare scratched simulated without inhibitor. Results presence significantly enhances %IE, up 99 %, steel. FESEM/EDS analysis further reveals substantially lower volume products area latter sample compared counterpart inhibitor-free solution. Furthermore, indicated by findings X-ray photoelectron spectroscopy (XPS), interactions N Fe atoms, acting donors acceptors, respectively, hold significant importance chemisorption process.
