Using　zirconia　toughened　alumina　(ZTA)　particles　and　Ni-Ti　complex　powders　as　raw　materials,　high-Cr　cast　iron　reinforced　by　ZTA　particles　was　prepared　by　an　infiltration　casting　process.　A　continuous　transition　layer　formed　at　the　interface　between　ZTA　particles　and　the　Cr15　matrix,　which　proves　that　there　is　strong　metallurgical　interfacial　bonding　at　the　interface.　The　phases　in　the　Ni-Ti　layer　of　the　ZTAP/Fe　composite　were　preserved　compared　with　the　microstructure　of　sintered　ZTA　ceramic　preform.　The　hardness　of　the　Ni3Ti,　TiO　and　AlNi2Ti　phases　in　the　interfacial　transition　layer　was　measured　by　the　nano-indentation　method,　which　is　12.5　GPa,　16.1　GPa　and　9.2　GPa,　respectively.　The　three-body　wear　resistance　of　the　composite　reached　12.6　times　that　of　high-Cr　cast　iron.　©　2019　by　the　authors.
