Carbon Nano Tubes

Metal Matrix Nano Composites (MMNC) consist of a metal matrix reinforced with nano-particles featuring physical and mechanical properties very different from those of the matrix. Especially carbon Nano tubes (CNT) can improve the matrix material in terms of wear resistance, damping properties and mechanical strength. The present investigation deals with the synthesis and characterization of aluminium matrix reinforced with micro B4C particles, and Multi Wall Carbon nano Tubes (MWCNT) were prepared by powder metallurgy route. Powder mixture containing fixed weight (%) of B4C and different wt% of MWCNT as reinforcement constituents that are uniaxial cold pressed and later green compacts are sintered in continues electric furnace. Microstructure and Mechanical properties such as micro hardness and density are examined. Micro structure of samples has been investigated using scanning electron microscope (SEM) .The results indicated that the increase in wt % of MWCNT improves the bonding and mechanical properties.

Matrix Nanocomposites

Aluminum based composites find diverse applications due to their superior mechanical and physical properties. Aluminum matrix nanocomposites have been synthesized with Al3Fe nanocrystalline intermetallics reinforcement using the powder metallurgy route. The prepared composites have been characterized for various physical and mechanical properties such as density measurement, bulk hardness, compressive strength, and tribological properties. The theoretical coefficient of the linear thermal expansion has also been predicted. The composite shows a high strength to weight ratio and excellent wear resistance, along with a low coefficient of friction. The observed wear rate is superior to other composites irrespective of the load and sliding velocity chosen for the study and it continuously decreases withan increasing amount of dispersoid.
