Study on Corrosion Behavior of 16MnR in the Circulating Water System

Abstract:

In order to know the corrosion behavior of 16MnR in the circulating water system and determine the influential sequence of factors, such as chloride ion concentration, temperature of circulating water, pH value and calcium ions concentration, to the corrosion of 16MnR. In this article, the electrochemical impedance test of 16MnR was conducted with electrochemical test system of CS310. The orthogonal test is adopted and the influential sequence of each factor to the corrosion of 16MnR is obtained by range analysis. The result shows that the impedance spectroscopy of 16MnR in the circulating water is a single capacitive reactance arc; the parameter which controls the corrosion process is the solution resistance R_P and with the increasing of R_P, the impedance value increases thus slowing down the corrosion velocity of 16MnR; the greatest impact on the corrosion of 16MnR are chloride ion and the temperature.
