Investigation of Mechanical and Tribological Properties of AA6061/MWCNT/B4C Hybrid Metal Matrix Composite

Carbon nanotubes (CNTs) and graphene, in particular, have been the subject of many recent studies since their discovery early 2000s. Because unusual properties, carbon piqued interest scientists across a wide range disciplines. An Al matrix was reinforced with powder metallurgy-fabricated B4C CNT composites. The nanocomposite aluminium examined for tribological behaviour, density, stiffness, compressive strength before after hot isostatic pressing (HIP). Scanning electron microscopy TEM were used to analyze hybrid counterparts (SEM). density nanocomposites reduced by 38% without HIP but 45% it added mixture. Hardness also increased 40%, following HIP, hardness rose 67%. Before compression 39% 60%, respectively. improves wear rate 45%, CNTs improve coefficient friction 20% all volume fractions only 48% case nanocomposites.
