Abstract
Nowadays the requirement for newer materials with improved properties for applications in automotive and aerospace industries are increasing and the composite materials are the solutions. In this work, characterization of 85.5 % pure aluminum with 10 % nickel and 4% cobalt, reinforced with various proportions of Multi Walled Carbon Nanotubes [MWCNT] is studied. Al-Ni-Co Metal Matrix Composite (MMC’s) are prepared by Powder Metallurgy (P/M) technique with 0.5, 0.75 and 1% of MWCNT addition. To investigate the effects of adding MWCNT particles, microstructural analysis, determination of mechanical properties and thermal conductivity are studied as per ASTM standards. From the Scanning electron microscope analysis, uniform distribution of MWCNT particulates are visualized inside the matrix of aluminum, nickel and cobalt. From the mechanical characterization techniques, it is observed that increase in addition of MWCNT, micro-hardness and compression strength increases, whereas thermal conductivity decreases. Thus the composite which will be used for the applications where light weight with high strength and hardness is required like airframe and aerospace applications.
