Abstract：The infiltration casting method is used for the preparation of threedimensional cocontinuous network SiC/cast iron composite material in atmospheric pressure. The friction and abrasion behavior of composite specimen in condition of dry sliding friction are investigated by pegtray friction abrasion tester. The antiwear mechanism of composite material is discussed. The results show that the wear resistance of the composite material is 4.7~7.9 times of gray iron, and average friction coefficient is 46%～89% of gray iron. The composite material provides with good antiwear property in condition of dry sliding friction.
