The　porous　ceramic　preforms　were　fabricated　by　firstly　mixing　the　ZTA　(ZrO　2　toughened　Al　2O　3)　ceramic　particles　of　1　to　3　mm　in　diameter　and　self-made　binder,　then　put　the　mixture　into　a　die　with　honeycombing　cavity,　and　finally　a　porous　ceramic　preforms　can　be　obtained　after　solidification.　ZTA　particle　reinforced　high　chromium　cast　iron　matrix　composites　have　been　prepared　successfully　by　pouring　the　liquid　metal　to　the　porous　ceramic　preforms.　The　three-body　abrasive　resistance　of　the　composite　has　been　investigated.　The　results　show　that　the　volume　fraction　of　ceramic　particle　in　the　composite　is　48%　to　58%,　and　the　interface　between　ceramic　particle　and　matrix　is　compact,　there　are　no　defects　such　as　porosity,　crack　and　so　on.　The　three-body　abrasive　resistance　of　the　composite　after　heat　treatment　is　5.9　times　higher　than　that　of　Cr20　cast　iron.
