【Abstract】 The experiments of three kinds of plants as corrosion inhibitors for steel in two kinds of acid liquids, were carried out respectively. Based on the polarized curve extrapolation, the corrosive current densities for steel in these acid liquids were obtained. Furthermore, the inhibition efficiency of these inhibitors was investigated. The experimental data showed that all the inhibitors have obvious inhibition on the steel corrosion in the acid liquids and their inhibition efficiency bepends on the acid liquids and the amount of the inhibitors.更多还原
