Abstract
Eight exhaust gas condensates were evaluated for their corrosiveness towards plain carbon steel, Type 1 aluminized steel, Galvalume, and Type 409 stainless steel. Test methods included the use of anodic polarization measurements and a cyclic immersion procedure. The corrosivity of an exhaust condensate is affected by its chemistry, which in turn may he affected by variations in fuel, engine operating conditions, type of engine, and the emission control system. Condensate pH of those tested ranged from 2.3 to 9.0. Results of the corrosion tests showed that acidic condensates were generally the most corrosive, but that substantial pitting corrosion could occur with alkaline condensates.
