Statistical analysis of wear in hybrid composites using Taguchi method

The wear behavior of hybrid metal matrix composites (HMMCs) has a major impact on their durability and performance in engineering applications. This study investigates the wear of hybrid metal matrix composites in parent metal aluminum alloy 6061 supplemented with boron carbide (B 4 C) and molybdenum disulfide (MoS 2 ) particles using a pin‐on‐disc tribometer. A structured experimental plan using the Taguchi L9 orthogonal array was implemented to investigate the effect of normal load (10 N, 20 N, 40 N), sliding speed (0.5 m/s, 1.0 m/s, 2.0 m/s), and sliding distance (500 m, 1000 m, 2000 m) on the tribological behavior of the composite system. The findings show that the wear rate is most significantly influenced by the applied force, which is followed by sliding speed and sliding distance. The contribution of each parameter to wear behavior was evaluated through analysis of variance (ANOVA). The incorporation of hard boron carbide and self‐lubricating molybdenum disulfide significantly improved the wear resistance of the hybrid composites. Their combination of strength and self‐lubricating properties makes them ideal for components such as brakes, gears, and marine parts. The Taguchi method proves to be an effective tool for optimizing process parameters and reducing experimental trials while ensuring robust results.
