The corrosion performance of aluminium-based hybrid composites, incorporating Boron carbide (B4C) and red-mud (RM) reinforcements, was explored using the Taguchi method in this analysis. The procedure employed to build composites with varying weight percentages of B4C and a consistent RM involved the application of stir casting. The corrosion performance of the composites was examined to investigate the influences of B4C weight percentage, solution normality, and immersion duration in an HCl solution. The specimens underwent testing in HCl solutions with normality values of 0.25, 0.5, 0.75 and 1, and were exposed for a period ranging from 24 to 96 hours. By utilising the design of experiments method and the Taguchi technique, the statistical analysis of the composites' corrosion characteristics was conducted. The corrosion behaviour of composites was investigated by employing signal-tonoise ratio and analysis of variance techniques to examine the impacts of different parameters. The outcomes demonstrated that the composites outperformed the monolithic alloy AL-6061 in terms of corrosion resistance. The corrosion rate and weight loss were significantly influenced by the solution normality, immersion duration, and percentage of reinforcement. Scanning electron microscopy serves to investigate the corrosion morphology.
