Metal matrix composites are heterogeneous systems containing matrix and reinforcement. They are used in automobile, aircraft and marine industries because of their increased corrosion resistance. In this paper weight loss corrosion tests are conducted onZA-27/ Red Mud metal matrix composites in different concentrated sodium chloride solutions. ZA-27 is the matrix and the reinforcement is red mud. Composites are prepared by liquid melt metallurgy technique using vortex method. The corrosion rate decreases with increase in the exposure time for all specimens in all corrodents. Corrosion rate also decreases with the increase in reinforcement content of the composites.
