Abstract
Abstract Researcheshave been conductedon corrosion, its effect on the metal used, and the factors affecting the corrosion resistance and methods of protection.Inmost of these researches ferrous and non-ferrous metal were tested in different water media. In this work , the corrosion ofgray cast iron, In drinking water (normal and magnetic), was studied using two methods. In the first method, the samples were immersed in water(normal and magnetic) for a differentperiods of time. In the second method the same number of samples were immersed in the water (normal and magnetic)for half an hour and dried for half an hour under the lab condition during the same above periods.A device was designed and manufactured for the immersion and drying purposes.The results showed that the corrosion rate of cast iron by the magnetic water is less than that by normal drinking water for both methods.
