“…Al2O3 particle reinforced iron matrix composites can improve the wear resistance, and these composites are better than the iron matrix [10,11]. Zirconia toughened alumina (ZTA) ceramics have a high hardness, better fracture toughness, and good thermal stability, and they are used as reinforcement in metal matrix composites [12,13].…”

Abstract:The abrasive wear resistance of zirconia toughened alumina (ZTA) ceramic particle reinforced high chromium cast iron (HCCI) composites has been systematically investigated using a moving wedge type of apparatus. The results of three-body abrasive wear show that the wear resistance of the composites with honeycomb is three times higher than that of the high chromium cast iron. The wear resistance of the composites with a honeycomb structure is close to that of the layer structure and is higher than that of the HCCI because the honeycomb wall in the cell honeycomb structure is prominent and because the honeycomb core is depressed. The wear mechanisms of the composites are mainly microcutting and fatigue fractures. The honeycomb structure forms a "macrocosmic shadow protection effect" and a "microcosmic shadow protection effect" to protect each composite and to improve the wear resistance of the composites.
