Abstract
: The effect of pores in Fe- Cu and Fe-Cu-C generated by sintering with solid state has been studied. The additive alloying elements Cu & C and the size of the pores were affected on wear rate, there for the carbon reduces wear rate, and larger pore lowing wear rate. Geometrical distributions of the secondary pores were independent on Cu and C fraction used. Structural materials sintered with solid state and Argon atmosphere (Ar), it seems therefore desirable to use as fine alloying powders as possible to attain optimum wear resistance. This work was done by two stages: First stage, pore formation during sintering with two different additive alloying elements Cu & C. While the second stage wear test was performed by using pin-on- disc machine for different loads (2, 4, 6 and 8 N) to each composite material used in this work under dry sliding conditions. The results showed that obviously improvement in wear resistance for C additive alloying element more than Cu.
