Abstract

The abrasive wear behavior of specimens of Fe-Al intermetallic compounds (Fe3Al, FeAl, FeAl2, Fe2Al5 and FeAl3) on SiC abrasive papers having an abrasive grain diameter ranging from 10 to 48 μm were investigated. The relationship between the wear rate and the material hardness is classified into two cases. In the first case, the wear rate increases with decreasing specimen hardness when the specimen is worn using an applied force of less than 0.31 MPa and an abrasive grain diameter finer than 30 μm. In this case, ductile wear is observed in all specimens. In the second case, the wear rate increases with increasing specimen hardness when the specimens are worn using an abrasive grain diameter coarser than 30 μm. In this case, brittle wear is observed in the FeAl2, Fe2Al5 and FeAl3 specimens.
