Abstracts

In this study, electrochemical measurements were carried out to characterize the inhibition efficiency of the commercial product Kemazur 1620, employed for water treatment in cooling circuits. The influence of parameters such as the concentration of the compound and the effect of the temperature on the behavior of the carbon steel / corrosion medium interface was studied. Polarization curves have been obtained by a three-electrode device. In the first part of this study, only the evolution of the corrosion rate as a function of concentration was examined. It has been shown from the polarization curves that the Kemazur 1620 presents a very good efficiency for a concentration of 2000 ppm. Between 1000 and 2000 ppm, the inhibition efficiency increases from 56 to 91 %. In a second part, the inhibition efficiency of the compound has been compared to an inhibitor used for similar uses.

Keywords

Inhibition, corrosion rate, electrochemical method, water treatment, Kemazur 162.
