Abstract:A comprehensive review on the research of ceramic/Fe-based alloy composites was offered. The focuses are placed on the types of recently developed fabrications of the ceramic/Fe-based alloy composites, interface between Fe- based alloy and ceramic, such as Al2O3, SiC and TiC, and the friction and wear behaviors of the continuous three-dimensional interconnected ceramic/metal and composites. The results show that the suitable process to fabricate ceramic/Fe-base alloy composites is pressureless metal-activated infiltration, surface metallization of ceramics and interface reaction control. The research topics on the ceramic/Fe-based alloy composites, should be focused on the interface problems of the ceramic/Fe-based alloy, inner structure of ceramic and metal, fabrications and friction and wear behaviors.
Key words: ceramic/Fe-based alloys; composites; wettability; friction; wear
