The resistance to wear by the erosion of hard particles of FeAl based cermets was evaluated. Cermets were produced by infiltrating either WC, TiC or TiB2 powder preforms with molten FeAl. Erosion testing was performed in accordance with ASTM standard G76-83, as Al2O3 particles entrained in a N2 gas stream impinged the surface of the wear specimens. Test were performed at 25, 180, 325, 500 and 700°C, and the wear was measured as material loss after a fixed erosion time. The wear of the FeAl-cermets was compared to the wear of WC-Co. It was found that for WC-Co wear resistance decreased (i.e, magnitude of wear/material loss increased) with increasing temperature; where as, for the FeAl-cermets, the magnitude of wear essentially remained constant with temperature. These results are discussed in terms of the mechanisms of material removal during the erosion process.
