摘要：

The effects that indolizine derivatives, a tellurium organic compound, rhodanine, sodium diethyldithiocarbamate, and some of their mixtures have on corrosion of steel in 1 M hydrochloric acid are studied by gravimetric analysis, kinetic measurements at different temperatures, polarization measurements, and impedance spectroscopy. The listed compounds and their mixtures are found to be effective inhibitors of acidic corrosion of low-carbon steel. In the presence of inhibitors, the corrosion of steel in hydrochloric acid is shown to be kinetically controlled. The considered additives have different influences on partial reactions in the corrosion process.
