“…Several methods were applied to produce the iron-based MMCs with enhanced properties, including casting (Li et al, 2007), laser cladding (Do Nascimento et al, 2008), tungsten inert gas (TIG), and some others (Korkut et al, 2002;Buytoz et al, 2005). By applying these methods, the reinforcing phases were often prepared separately prior to composite fabrication; however, the thickness of the reinforcing phases was limited by the starting powder size.…”

“…Similarly, for the metal matrix between the ZTA particles, the matrix has a high toughness that can hold the ZTA particles firmly. In turn, the ZTA particles can prevent the abrasive particles from cutting on the metal matrix, called microcosmic shadow protection effect [21,31]. For the ZTA P /HCCI with honeycomb structure under the condition of different hardness and different size of the abrasive, the honeycomb wall and honeycomb core are protected by macrocosmic shadow protection effect and microcosmic shadow protection effect that results in improvement of the abrasive wear resistance of the composites.…”

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.

“…Therefore, iron and steel matrix composites are proposed and considered to be a new choice to substitute traditional metal materials due to the synergetic effect caused by the combination of desirable properties of the reinforcement and metal matrix [3,4]. In recent years, researchers investigated various iron and steel matrix composites, such as TiC-Stainless steel composite [5,6], WC/Fe composite [7,8], and ZTAp/iron composite [9]. Among these composites, ZTA particle reinforced iron matrix composite is a promising wear-resistant composite material, in which ZTA particle has a high hardness and toughness, thermal shocks resistance, and a relatively close thermal expansion coefficient with iron [10,11].…”

In this paper, a two-step method, rapid-flow mixing followed by high-pressure compositing was used to prepare a macro-ZTA (ZrO2-toughened Al2O3) particles reinforced high chromium cast iron (HCCI) matrix composite. The method is based on the squeeze casting process without general casting pollution problems. The microstructure, mechanical properties and dry sliding wear performance of the fabricated composite were investigated. The results showed that the particles were distributed uniformly throughout the iron matrix and a tightly bonded interface was obtained. Under dry sliding wear conditions, the wear resistance of the composite was significantly improved in comparison with the HCCI alloy, and the relative wear resistance was 1.8 and 2.9 times at the applied load of 300 and 900 N, respectively. When the load increased from 300 N to 900 N, the wear characteristics of the composite changed from shallow and narrow grooves and scratches to damages in the form of fragmentation of particles, transfer layer and interface cracking.
