We report here improved abrasive wear resistances for our newly developed bulk polycrystalline age-hardened/toughened MgO-MgFe2O4 ceramic alloys. In comparison with phase pure MgO, reductions in wear rates by up to similar to 30% were recorded for the MgO-MgFe2O4 alloys, with those developed upon aging at 1000 degrees C for 0 h showing the best improvements. In contrast to the worn surfaces for MgO, the worn surfaces of the alloys showed the presence of only abrasive grooves with hardly any evidence for brittle fracture induced pull-out. Estimates for area fractions of pull-outs and depths of damaged zones present trends similar to the wear rates, with the pull-out fractions and the depths of damaged zones being lesser for the MgO-MgFe2O4 alloys by up to similar to 60% and similar to 70%, respectively, as compared to phase pure MgO.
