Evaluation of Atmospheric and Aqueous Corrosion of Passenger Car Body in Mosul City through the Year 2009-2010

Corrosion of five steel bodies of passenger cars of models 1985, 1990, 1995, 2000, &2005 that are used in Mosul city were studied under atmospheric and aqueous during2009-2010. Atmospheric corrosion rates were below 1.7 mpy, which is classified as lowcorrosion, this is due to dry weather conditions during the study period , and the qualityof steels of the car bodies. Aqueous corrosion rates were also low, below 4.57mpy, andthis is due to good water quality of Mosul , low Langelier saturation index, idealcorrosion index, and the quality of steel body cars.Key Words: Mosul city, Atmospheric Corrosion, Car Body Steels, 2010.
