Description
Summary:The combination of the lightweight nature and mechanical properties of AZ91 makes it a suitable material for defense, aerospace, and automotive components. The study of the friction and wear properties of AZ91 contributes to the understanding of interactions of surfaces in relative motion. Hybrid ceramic reinforced composites can be tailored to offer enhanced mechanical and tribological properties. The present study highlights the development of AZ91-based hybrid composites reinforced with nano hBN and micron-sized TiB<sub>2</sub> ceramic particles. The hBN is used as a hybridizing agent in the perspective of improving the friction and wear behavior of the composites. The Taguchi L16 orthogonal array was used to prepare the experimental plan. The normal load, sliding speed, and sliding distance were considered as influencing factors in the experiments against the responses, wear rate, and coefficient of friction. Multi-Criteria Decision-Making methods such as Additive Ratio Assessment System (ARAS) and Weighted Aggregated Sum Product Assessment (WASPAS) were employed to optimize the experiments. The presence of hBN decreased the wear rate and coefficient of friction of the hybrid composites. The adhesive mode of wear mechanism was found to be operative in the composites.
