Abstract

Cold Isostatic Compaction Chamber is used for various applications such as sparks plugs and insulators. Cold Isostatic compaction process results in better and more uniform properties as compared to die compaction because of uniform application of pressure from all directions and absence of die wall friction. Al-NanoAl2O3 composites with various weight % of NanoAl2O3 were fabricated using powder metallurgy process through cold Isostatic compaction chamber. The various properties viz. hardness, density, porosity, compressive strength, indirect tensile strength and surface roughness were measured. The microstructure of polished and etched surfaces of powder metal Al-NanoAl2O3 composite samples was studied using scanning electron microscope.
