Abstract

To simulate conditions for evaluating the inhibition efficiency of an IFKhAN-114 volatile inhibitor under atmospheric corrosion of copper in the presence in the air of two corrosion promoters CO2 + NH3 or H2S + NH3, polarization measurements were performed. For this purpose, 0.1 M NaCl solution containing, in a wide range of concentrations, the products of the hydrolysis of ammonium carbonate or ammonium sulfide was used. Comparison of the data obtained through weight loss tests (the first method) and polarization measurements (the second method) showed that the latter approach allows obtaining only qualitative data, which, however, requires significantly less time than the first one.
