Abstract
Abrasion resistance is one of the least studied properties of refractories despite its significant contribution to wear mechanisms. This work investigated the abrasion resistance and Vickers hardness of ZnO+Fe2O3 (3:1 by weight) doped alumina-rich spinel and magnesia-spinel that contained multicomponent (Mg,Zn)[Al,Fe]2O4 spinel as a major and minor phase, respectively. Sintered Al2O3, MgO-stabilized ZrO2 and MgO were used as standard reference refractory raw material aggregates for comparison. Stationary samples at room temperature were rubbed against a vertically rotating rubber lined wheel on which SiC particles were fed. This abrasion test revealed that (Mg,Zn)[Al,Fe]2O4 spinel occurring as individual grains along with sub-micron precipitates within magnesia grains increase abrasion resistance as compared to MgO. Microstructure of abraded surfaces identified wear mechanisms like microcracking, grain pullout formed craters, abrasion grooves and scraped patches. 3 wt% doped magnesia-spinel and 34 wt% doped alumina-rich spinel were found to be promising wear resistant matrix compositions to make environment-friendly chromium-free refractories for the copper industry.
