Abstract :

[en] Porous grey cast iron powder metallurgy parts were made from grey cast iron powder manufactured via target jet milling of machining scraps. The powders were used in the as-milled state without any further physical or heat treatment. Sintering was conducted at 1025, 1100 and 1175°C in an argon atmosphere and the effect of sintering temperature on microstructure, sintered density and apparent hardness of the grey cast iron specimens pressed to 5.8g/cm3 was investigated. Although diffusion processes were partially activated at 1025°C, it was determined that a temperature of 1175°C proved to be the ideal temperature for solid state sintering of grey cast iron parts. The hardness value and sintered density for the specimens sintered at 1175°C were found to be 96 BHN and 6.1g/cm3 (around 15% porosity) respectively, all of which lends itself to promising properties for making self-lubricating bearings and parts with sliding properties. © 2012 Elsevier Ltd.
