Effect of Sicp on the Microstructure and Mechanical Properties of Sintered Distaloy DC Composites

Different PM steels have found applications, mainly in the automotive industry for engine and transmission systems. In this paper examined in research on the microstructure and mechanical properties of Distaloy DC + 0.5%C + %0.6 introlube® with addition the silicon carbide. Specimens were prepared from diffusion alloyed Distaloy DC (Fe-2 wt. % Ni-1.5 wt. % Mo) mixed with graphite. SiCp in proportion to 0.5 and 1 wt % was added to the powder-graphite mixtures. In this work the Distaloy DC+ 1 wt % SiC is the best composition, because it presented the highest wear resistance and good hardness.
