Abstract
The aim of this work is to study the effect of aluminum, Tungsten and cobalt on the mechanical properties of iron based composites. Five samples were prepared by milling for 20 h followed by cold pressing then sintering at temperatures range from 1000 to 1250 °C. The samples were characterized using density measurements, SEM, Wear test and friction coefficient measurements. Sample five (5%W, 4% AL and 1% CO) showed the highest wear resistance, largest hardness, fine grain size and the lowest friction coefficient compared with other samples which recommend this sample to be a good candidate for applications require high wear resistance and moderate friction coefficient.
