WC reinforced high-Cr white cast iron matrix composites with honeycomb-shaped ceramic plates are prepared by the common infiltration casting technique.Structure and phases of the interface are investigated with optical microscope and X-ray diffraction(XRD).The dissolution and diffusion of the WC particles in the hot metal form an interlayer,which ensure metallurgical bonding of the interface between the high-Cr white cast iron and the particles.Wear performance of the composite with honeycomb hole are studi...
