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


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