Abstract

The effect of carbon addition on tribological properties of a series of Fe-Al alloys was discussed. The addition of carbon in Fe-Al alloys resulted into the formation of Fe3AlC0.5 or graphite in the matrix, depending on the Al content. The tribological properties of high carbon Fe-Al alloys were compared with those of cast iron. Optical micrographs of the carbon-added Fe-Al alloys after homogenizing treatment were also presented. The addition of carbon was found to be effective in improving the room-temperature tribological properties of Fe-Al alloys, but had negative effect on the tribological properties at elevated temperatures.
