Study of EMISE Ionic Liquids Inhibitor on the Corrosion Behavior of Steel Rebar by Statistical Methods in Alkaline Chloride Solution

Abstract

The pit corrosion behavior of steel rebar in alkaline chloride solutions without and with EMISE ionic liquids inhibitor were investigated by means of electrochemical noise (EN). The experimental results of electrochemical noise measurement revealed that the pit corrosion was inhibited and corrosion pitting process was retarded significantly. The mechanism of the inhibition effect of the inhibitor was analyzed based upon the combined stochastic theory and shot noise theory using the Weibull distribution and Gumbel distribution function.
