Increased Porosity and Their Effect on The Density and Hardness Value of (Ni—Cu) Alloy

Engineering and Technology Journal, 2011, Volume 29, Issue 1, Pages 66-74

This research is aimed to produce Ni-Cu alloys by powder metallurgy method
because its commercial and technological importance. Nickel and Copper powders
were tacked then their powders mixed and blended together and classified to four
parts, Sodium Chloride powder added (as a space holder) to three parts and the
last remain as it is then these powders mixed and then compacted in hydrostatic
pressure at 7ton, then this compact samples were sintered in furnace under argon
gas at 950°C for one hour, latest these samples are grinded and polished to
examine the microstructure, density, porosity, microhardness, X-ray diffraction
and corrosion resistance.
