Effect of Electroless Copper Coating on the Corrosion Behavior of Aluminium Based Metal Matrix Composites Reinforced with Silicon Carbide Particles


The present paper involves firstly in the studies of corrosion properties of Al 6061 metal matrix composites reinforced with varying percentage of uncoated and Cu coated silicon carbide in 3.5 wt% NaCl solution using weight loss method. The processing route used for the composites was stir casting technique. Mass loss and corrosion rate measurements were utilized as criteria for evaluating the corrosion behavior of composites. The surface morphology of composites after the corrosion test is determined by using scanning electron microscopy. It has been observed that copper as reinforcement coating reduces the corrosion resistance of composites in comparison to uncoated reinforcements and monolithic alloy.
