“…The decreasing trend is owing to the rise in the hardness of the composite materials with the addition of hard Si 3 N 4 particles [ 22 ]. In general, the wear resistance offered by the harder material is much higher than that of the softer material [ 29 ]. The hard primary reinforcing material acts as a hurdle for the deformation and, therefore, more energy is required to deform the base alloy matrix material.…”

Hybrid aluminium metal matrix composites have the potential to replace single reinforced aluminium metal matrix composites due to improved properties. Moreover, tribological performance is critical for these composites, as they have extensive application areas, such as the automotive, aerospace, marine and defence industries. The present work aims to establish the tribological characteristics of Al7068/Si3N4/BN hybrid metal matrix composites prepared by stir casting route and studied using a pin-on-disc apparatus under dry sliding conditions. The hybrid composite samples were prepared at various weight percentages (0, 5, 10) of Si3N4 and BN particles. To investigate the tribological performance of the prepared composites, the wear experiments were conducted by varying the load (20, 40 and 60 N), sliding velocity (1.5, 2.5 and 3.5 m/s) and sliding distance (500, 1000 and 1500 m). Wear experimental runs were carried out based on the plan of experiments proposed by Taguchi. The minimum wear rate was found with the composite material reinforced with 10 wt. % of Si3N4 and 5 wt. % of BN. Analysis of Variance (ANOVA) was employed to analyse the effect of process parameters on wear rate and coefficient of friction (COF). The ANOVA test revealed that the weight fraction of Si3N4 has more of a contribution percentage (36.60%) on wear rate, and load has more of a contribution percentage (29.73%) on COF. The worn-out surface of the wear test specimens was studied using its corresponding SEM micrograph and correlated with the dry sliding wear experiment results.

This study involves the preparation of in situ TiC-reinforced zinc-aluminum alloy (ZA-37) composites and analysis of their high-stress abrasive wear behavior. The wear rate, friction coefficient, and frictional heating of the composites are investigated using a pin-on-disk wear tester. The experiments are carried out based on a plan created using Taguchi's technique. TOPSIS methodologies are used to determine the effects of applied load, abrasion distances, TiC contents on wear rate, coefficient of friction, and frictional heating throughout the wearing process. The results reveal that the composite with 10 wt% TiC exhibits the highest level of wear resistance among all samples. It is found that ploughing, microcutting, and delamination were the dominant wear mechanisms in general. However, in the optimum combination, mild abrasion and microploughing prevail. As per TOPSIS analysis, the reinforcement content affects the wear rate of test materials the most followed by applied load and abrading distance. Under the optimal combination of parameters, the in situ TiC composite has the potential of replacing the conventional gray cast iron utilized in bearing applications.
