Ni-encapsulated ZTA (ZTA@Ni) particles as precursors to reinforce high chromium cast iron (HCCI) matrix composites are synthesized by electroless deposition using a choline chloride-ethylene glycol (ChCl-EG) ionic liquid additive. The effects of NiSO 4 concentration, ChCl-EG concentration, reaction temperature, and ZTA loading capacity on the surface morphology, coating thickness, and elemental distribution of the ZTA@Ni particles are investigated. The deposition sequence of the Ni coating layer is analyzed according to changes in the morphology of samples obtained at different reaction stages. A schematic illustration of the deposition process with the ChCl-EG additive is established. It is demonstrated that ChCl-EG plays the important role of hindering the fast nucleation and crystal growth of Ni nuclei. In addition, the abrasive wear resistance of the ZTA@Ni-reinforced HCCI composite is higher than that of the matrix and the ZTA-reinforced composite. Close contact between the ZTA@Ni particles and the matrix benefits load transfer from the matrix to the reinforcement. The diffusion of metallic Ni leads to the formation of numerous nuclei to refine the particle size of carbides adjacent to the interface and reinforce the interfacial bonding strength.

“…Some studies have found that the contact angles of Fe/Al 2 O 3 and Fe/ZrO 2 reach 140°and 116°, respectively [11,12].This shows that the interface bonding ability between Fe and the two ceramic materials is very poor. Therefore, it is necessary to modify ZTA particles by metal coating [13].…”

“…Electroless plating is widely used as a surface metal coating treatment method in the manufacture of cermets [13][14][15][16].The metal coating on the ceramic surface is mutually soluble or reacted with the matrix metal to obtain a mechanical bonding interface or a reaction bonding interface to achieve a wetting effect. Ru et al [16] found electroless plated Ni and Cr on the surface of ZTA, and Ni and Cr diffused into the iron matrix under high temperature conditions, forming a diffusion interface layer, which improved the wettability of ZTA and matrix.…”

The cermet based on metallic iron with zirconia toughened alumina (ZTA) as the reinforcing phase was prepared by vacuum hot-pressed sintering. The ZTA particles were subjected to electroless nickel plating to improve the interfacial bonding ability of ZTA and Fe matrix. In this paper, after electroless nickel plating, the effects of different particle sizes and different contents of ZTA particles on the grinding properties of Fe-based ZTA (Fe-ZTA) cermets were investigated. The results show that the ZTA particles are tightly bound to the Fe matrix. An interface layer is formed between the ZTA particles and the Fe matrix and it can improve the grinding ability of the Fe-ZTA cermet. By reducing the particle size and the content of ZTA particles, the friction coefficient between Fe-based ZTA cermet and the machined surface can be increased, and the surface roughness of the machined surface will reduce. When the ZTA particle size is F14 and the iron binder content is 40%, the friction coefficient between the Fe-ZTA cermet and the steel bar is 0.4981, the surface roughness of steel bar is 40.164 μm, the grinding ratio is 685.952.

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.
