Abstract

The tribological characteristics of Hybrid Metal Matrix Composites (HMMCs) are examined in this work. The Al6061 alloy used in the research of hybrid metal matrix composites is reinforced with 4 % B4C and 1 % MoS2 using a variety of stir casting techniques, including vacuum casting, rotary casting and squeeze casting. The Pin-on-Disk test examines wear with an emphasis on adhesive wear, abrasive wear, and weight loss using several factors. Also, the friction force is measured in relation to the wear loss. The purpose of the study is to evaluate how various casting techniques affect the material's wear resistance, friction force and connect it to worn surface morphology characteristics.

Keywords: • Hybrid Metal Matrix Composites (HMMCs) • stir casting • tribology • wear • friction • worn surface morphology • pin-on-disk
