Recent developments in fabrication of ceramic particle reinforced iron matrix wear resistant surface composite using infiltration casting technology

Abstract: Ceramic particle reinforced iron matrix composites are one of the most promising wear resistant materials for tough conditions. Up to now, varieties of methods have been developed to fabricate this material, e.g. the infiltration casting process, which is especially beneficial to prepare the surface composite. Based on this method, a honeycomb structure of surface composite has been designed aiming to increase its toughness and interface strength. Moreover, zirconia toughened alumina (ZTA) is a perfect choice … Show more

“…In situ and ex situ methods could be applied to fabricate the composite reinforcement [10][11][12]. In the ex situ methods, the ceramic is previously produced with the required shape and then inserted into the mold [11,[13][14][15][16][17][18][19][20][21][22], while in situ methods aim to produce the ceramic particles through the combustion reaction of the powder compacts inserted in the mold cavity [23][24][25][26][27][28].…”

“…Due to the high hardness, high wear resistance and good fatigue performance, iron-based cermets have attracted more and more attention in the field of tool manufacturing and high wear resistance tools in recent years [1][2][3].The current research focus on how to use the reinforcement phase to improve the hardness and wear resistance of Fe-based cermets [3]. Ziejewska et al [4] found that the interface between the reinforcing phase and the matrix and the content of the reinforcing phase have an important influence on the grinding performance of the cermet.…”

“…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. In the existing literature, most of the Fe-ZTA cermets are prepared by molten metal die forging process [2,17,18], and the prepared Fe-ZTA cermet is often used to prepare wear-resistant materials, but the molding rate is low. The preparation of Fe-ZTA cermet material by powder metallurgy can effectively solve the problem of low molding rate of cermet and can achieve densification [19][20][21][22].…”

“…The wear behavior of components made of high-Cr WCIs can be more improved by ceramic reinforcement of the surfaces that will be exposed to wear, maintaining the toughness of the bulk component [9][10][11][12][13][14][15][16][17]. Among the reinforcements that can be applied, WC particles are the most used, combining high hardness (3100-3600 HV), thermal expansion coefficient (4.5-7.1 × 10 −6 • C −1 ) compatible with the base metal (8-12.5 × 10 −6 • C −1 ), higher elastic modulus compared with other transition metal carbides and good wettability by molten iron [18][19][20].…”
