- Abstract
Erosion Corrosion is the degradation of material by means of combined effect of mechanical flow and chemical reactions with the surrounding environment. Light weighting of automobiles has been a critical issue in the transportation industries. Magnesium alloy seems to be the best promising next generation's material and as a substitute to aluminium alloy and steel that are being used in automotive, aerospace industries. In this study ,Magnesium,AZ31 and AZ91 were used to investigate the erosion corrosion rate and corrosion rate in 3.5% wt NaCl .The experiments involved the measurement of weight loss .Experimental setup was used to carry out the erosion corrosion test. Immersion test was conducted to determine the corrosion rate. Results include erosion corrosion analysis, comparative analysis of erosion corrosion and corrosion rate. Further SEM analysis was done to study the microstructure behaviour of the samples. It was found that the corrosion rate increases as time of exposure increases. It was also inferred that the erosion corrosion rate is higher than corrosion rate due to moving fluid under the same environmental condition.
