Under-Deposit Corrosion Rate Evaluation in Cooling Water System by Weight Loss, Profilometric and Electrical Resistance Methods

Abstract:

Under-deposit corrosion in cooling water system is often found in industries. The under-deposit corrosion rate in cooling water system is rarely found in a literature. The mechanism depends on the metal, types of deposit and corrosive species in the cooling water system. In this study, the under-deposit corrosion rates of carbon steel in cooling water at various times were determined by weight loss, profilometric and electrical resistance methods at 40C. From this experiment, these three methods showed the consistent results. The under-deposit corrosion rates of carbon steel were about 0.1-0.2 mm/y.
