It is of great significance to clarify the corrosion mechanism rust layers on bronze ware for appropriate conservation measures. In this study, behavior Cu-Sn alloys in a 3.5 wt.% NaCl solution and simulated archaeological soil was studied compared using electrochemical measurements, microscopic observations, X-ray diffraction (XRD), photoelectron spectroscopy (XPS). The results showed that presence Cl− key factor leading formation harmful such as Cu2(OH)Cl3. solution, rapid accumulation Cl-containing products provided certain degree protection alloys, but easily fell off, thus increasing continuous reactions again. This resulted significant increase rate alloy (icorr from 4.845 μA·cm−2 27.21 μA·cm−2) decrease polarization resistance (Rp 5.17 kΩ·cm2 3.27 kΩ·cm2). contrast, were dominated by complex ions other than environments, tended form stable dense always lower 1.6 μA·cm−2, Rp maintained above 24 kΩ·cm2), which improved two orders magnitude unstable layer formed solution. addition, boosted wettability layers, thereby facilitating penetration corrosive media strengthened reactions. study deepens our understanding degradation mechanisms artifacts provides scientific basis developing strategies.

Pyridine and urea derivatives have emerged as valuable corrosion platforms ascribed to exceptional coordination potential, environmental friendliness. Two novel structures of pyridine-carbamides (MS30 & MS31) were synthesized used green inhibitors for the carbon steel in 1M HCl. Electrochemical measurements determined increase efficiency with concentrations, reaching 95.3% 97.1% at 200 mg L −1 298 K MS30 MS31. Despite reduced performance increasing temperature 303 313 K, results revealed improved inhibition 323 K. At highest MS31 proved their influence maintaining 97.6% 93.4% efficiency, highlighting suitability treatments oilfield downhole regions. The adsorption both fitted Langmuir model was attributed chemisorption, inferred from thermodynamics. Corrosion kinetics activation energy also verified chemical interaction Fe–inhibitor complex. Spectroscopic surface evaluation interpreted surpassed metallic dissolution by through protective barrier formation, X-ray photoelectron spectroscopy (XPS) existence Fe–N bond. sustained viability human cells affirmed nontoxic nature after treatment 0.2 mL−1 compounds. DFT calculations that exhibited strong on metal (− 9.5 eV), classified chemisorption. Overall, experimental findings are well supported computational studies. These pioneering compounds introduced herein advance state-of-the-art inhibitors, providing high under challenging environments.
