Wide range of industrial and engineering applications for graphite containing cast irons and the harmful effects of corrosion environments on these important engineering materials, make it necessary for continuous Scientific research in this field . In the current study, performed corrosion tests on Pearlitic cast irons using the sandy soil as the corrosion environment .
The results obtained show a clear relationship between corrosion rate of graphite containing cast iron with shape of graphite. The graphite flakes in cast iron appeared to cause high corrosion rates compared with spheroidal or rosette graphites . The results also show that corrosion rates of spheroidal cast iron are slightly higher than malleable cast iron. The corrosion rates of grey cast iron represent the highest when compared with those of spheroidal and malleable cast iron.
