A review of recent developments in the corrosion performance of aluminium matrix composites

The necessity to reduce fuel consumption and gas emissions has revealed the need to use materials with high specific strength. Aluminium (Al) matrix composites are widely used in aerospace, automotive and defence industries due to their low density, high strength and good wear resistance. Knowing the effect of reinforcement materials on the corrosion performance of Al matrix composites is essential for estimating service life. This review focuses on the recent corrosion studies of Al matrix composites. Researchers have performed different corrosion tests such as potentiodynamic, electrochemical impedance spectroscopy, immersion and salt spray to explore the corrosion rate. The effect of the reinforcement type and content on the corrosion performance of the Al matrix composites is reviewed. This review also explains the reasons for the increase/decrease in corrosion resistance and damage mechanisms.(c) 2023 Elsevier B.V. All rights reserved.
