Metal matrix composites consist of reinforcement and matrix in a heterogeneous system. It is possible to modify their mechanical and physical characteristics to meet specific needs. They are used in the automotive, aviation, and marine sectors due to their enhanced resistance to corrosion. The liquid melt metallurgy process uses the vortex method to produce composites. The preparation of composites with 2, 4, and 6% weight percentage TiO2 follows ASTM standard G69. Specimens are prepared and machined using standard metallurgical procedures. In this study, Al6061 with TiO2 matrix composites is examined for static weight loss corrosion, potentiodynamic polarization, open circuit potential, scanning electron microscopy and energy dispersive spectroscopy in corrosive environments of 0.05M and 0.1M NaOH. Corrosion rates decrease as exposure time increases for all specimens in all corrodents and testing procedures. In composites, the rate of corrosion reduces as the reinforcing content increases.
