Improvement of Corrosion and Erosion Resistance Properties for Cast Iron

Abstract

Abstract Cast iron is considered a very common material for manufacturing applications due to its low cost, easy casting and high stress compression sustains. One of the obstacles in the application of cast iron are the corrosion and erosion phenomena which limits using the cast iron in certain applications. To improve the resistance rate of cast iron to corrosion and erosion. Chromium material had been added to the gray cast iron as a function of weight with different ratios to check which ratio is perfect to increase its resistance. The effect of corrosion and erosion on cast iron was investigated experimentally with and without chromium additives on the resistance of gray cast iron with and without chromium additive. Results showed that the mechanical properties increased with the increase of the chromium ratio in the four cases in general to minimize the risk of material destruction from erosion-corrosion.
