Abstract

Great progress has been achieved in the preparation of ZTA（zirconia toughened alumina）ceramic particle reinforced iron matrix composites by infiltration method.The research progress was reviewed for ceramic preform preparation

infiltration of liquid iron into ceramic preform

wettability of ceramic and liquid iron

interfacial bonding of composite materials and wear resistance of composite materials.It is concluded that the wettability of molten iron with the preform is a prerequisite for the realization of infiltration.The common methods include adding active elements to ceramic preform

modifying ceramic surface by electroless plating

vapor deposition and coating

etc.The formation of transition layer between ceramics and metal matrix can improve the structure of interface and promote metallurgical bonding between ceramics and metal matrix.The infiltration mechanism of molten iron into ceramic preforms and the wear resistance mechanism of ZTA ceramic composites need to be further analyzed.
