 This paper deals with the high corrosion resistance developed by the metal matrix composites when compared with that of matrix alloy by open circuit potential test. Matrix selected is AL6061 and reinforcement selected is quartz particulates, which is a ceramic material. The composites are prepared using liquid melt metallurgy technique using vortex method. Metal matrix composites containing 2, 4 and 6 weight percentage of quartz are casted. Castings of composites and matrix are cut into rectangular specimen of 20mm x 20mm cylinders for weight loss test according to standard metallographic techniques. Microstructures of the specimens are taken. The corrodents used for the tests were 0.025, 0.05 and 0.1 molar sodium hydroxide solutions in which weight loss corrosion tests were conducted at room temperature. Effect of exposure time and presence of increased percentage of reinforcement red mud and concentration of the medium are discussed in detail.
