Abstract

A ceramic/cast iron composites of ZTA/high chromium cast iron was fabricated successfully by pressureless infiltration with high chromium cast iron on the ZTA preform with 5%Ti particles.The microstructure

element composition and phase constituent of the composites were investigated by scanning electron microscopy（SEM）equipped with energy X-ray dispersive spectroscopy（EDS）system and Xray diffraction（XRD）.The results show that high chromium cast iron can be spontaneously infiltrated into the ZTA preform with 5%Ti particles and homogeneously distributed in the composites.Ti particles in the ZTA preform and Cr elements in the alloy promote jointly role for pressureless infiltration process.Moreover

the interfacial reactions occur between the alloy and the preform

and the reactive products are FeAl

intermetallic and FeTiO

、AlCrO

solid solution.
