Analysis of Corrosion Growth of Ductile Iron in Different Environments

Article Preview

Abstract:

Ductile Iron has been a great material in water carrying pipes, heavy duty parts of farm equipment and other heavy applications. This work looked into the corrosion rate of ductile iron in different environments of usage and storage for a period of six (6) months. The environments were outside air, air conditioned (A/C) environment, brackish (salty) and alkaline environments. The results showed that as the period of exposure increases the corrosion rate decreases. There was a sharp corrosion rate at the first few months for all the environments but as the month increases the corrosion slows down. Brackish (NaCl) environment had the highest weight loss with a difference (last month initial month) of 1.1456g followed by outside environment with a difference of 1.0284g while A/C had the lowest with zero.
