ABSTARCT In this paper, we have studied the wear and frictional properties of the Al-Fe composite materials. The composite materials with 6.23 and .2 % Fe was prepared by the liquid metallurgical method. XRD and SEM technique were used to study the morphological character of the as-cast composite materials and subsequent forged by pneumatic hammer to homogenize the structure of the material. The optical and SEM results showed homogeneous dispersion of iron particles in the matrix. A dry sliding

... wear tests of as cast and forged samples was conducted on pin-on-disc machine over wide ranges of applied load and sliding speed. To determine the wear mechanisms, the worn surfaces of the samples were examined by SEM. Debris and wear tracks have been studied in detail to analyze the surface effects during dry sliding and to correlate wear properties. Observations from the experiments showed that the wear mechanism is dominated by oxidative debris under low loads and sliding velocities and wear tracks were largely covered with a smooth oxide layer.
