In this work, properties of three sintered and steam treated alloyed irons
were analysed. These materials were Fe+2Cu, Fe+0.6C+0.5Cu, and Fe+0.45P+2.5
Cu, which were obtained by powder mixing. Once pressed and sintered, sample
s were steam treated (surface treatment which is characteristic of sintered
irons). Density, hardness and tensile strength were obtained on sintered a
nd steam treated samples, within their microstructure analysis. Also, a tri
bological study was carried out since some parts of shock absorbers are wor
king under friction.
