The interfacial transition zone (ITZ) in the zirconia toughened alumina (ZTA) ceramic particles reinforced the high chromium cast iron composites was studied. The main phases are Na4SiO4 and 3Al3O2·2SiO2 in the ITZ were identified by XRD, TEM, and HRTEM. The hardness and the elastic modulus of the ITZ were examined by nanoindentation test are 7.11 GPa and 202.68 GPa, respectively. The results show that the Fe and Mn diffused from the ZTA particles and matrix into the ITZ. The interface bonding strength of ZTA/ITZ and ITZ/matrix is stronger than the middle region of the ITZ.
