ABSTRACT

In this research work, two coupons of equal mass were immersed in saline and fresh water environment respectively. The immersed coupons were observed to have lost weight. Their weight loss which was as a result of corrosion was measured periodically at intervals of one week for a total period of two months. The corrosion rates of the two different environments were then determined and compared accordingly. The fresh water, specimen the corrosion rate was slightly high in the beginning of the experiment but then continued at an approximate constant rate with an increase at the last week of the experiment, the low number of ions in the waters were responsible for this behavior since the available oxygen and the medium will form a corrosion cell and initiate the corrosion process until passive films were formed then rate became constant The examinations show that the corrosion rate in a saline environment is double of the corrosion rate in a fresh water environment.
