Isatin compounds as corrosion inhibitors for N80 steel in 15% HCl
چکیده انگلیسی
The inhibition effect of two synthesized isatin compounds namely 1-morpholinomethyl-3-(1-N-dithiooxamide)iminoisatin [MMTOI] and 1-diphenylaminomethyl-3-(1-N-dithiooxamide)iminoisatin [PAMTOI] on the corrosion inhibition of N80 steel in 15% HCl solution was studied by polarization, EIS and weight loss measurements. It was found that both the inhibitors were effective and their inhibition efficiency was significantly increased with increasing concentration. Polarization curves revealed that the used inhibitors represent mixed-type inhibitors. Adsorption of these inhibitors led to a reduction in the double layer capacitance and an increase in the charge transfer resistance, and was found also to obey Langmuir isotherm.
