چکیده انگلیسی
Herein, the corrosion behavior of Monel alloy was comprehensively studied in 5% HCl solution. Then self-adsorption of pyrrolidine dithiocarboxylate (PDTC), as a corrosion protector, on Monel surface was investigated. Electrochemical methods, such as CV, LSV and EIS, and surface techniques such as SEM and EDX were used for evaluation of PDTC-SAM on Monel. Obtained results showed the corrosion current density (Jcorr) decreased in 5 orders, the slope of Tafel plots increased, the corrosion potential (Ecorr) shifted to positive values, the corrosion rate (CR) decreased from 2.11 to 0.172â¯mm/yr, and the PE% as 91.9% was observed after 4â¯h self-assembling time.
