Based on fusion bonding and atomic interdiffusion between the liquid ceramic and Ti alloy

the laminated composites of the solidified TiB2 matrix ceramic with Ti-6Al-4V alloy were prepared by reaction processing in high-gravity field.XRD（X-ray diffraction）

FESEM（field emmission scanning electron microscope） and EDS（energy dispersive spectrmeter） results show that intensive self-toughening mechanisms initiated by fine platelets of TiB2 primary phases in the solidified ceramic presents a excellent combination of high flexural strength and high fracture toughness of TiC-TiB2 solidified fine grain ceramic composites.Meanwhile

as a result of fusion bonding between the liquid ceramic and Ti alloy in thermal-vacuum circumstances induced by reaction processing in high-gravity field

followed by intensive atomic interdiffusion between the liquid ceramic and liquid titanium

peritectic reaction of the solidified TiB2 and liquid Ti occurs at the final stage of material solidification

followed by direct growth of TiB solids from liquid Ti and subsequent eutectic reaction of TiB solids and liquid Ti

finally

the compsoites of the solidifed ceramic with Ti alloy were prepared in multiscale（micrometer/submicrometer/micro-nanomter） and multilevel（TiC-TiB2/TiC1-x-TiB-TiB2/TiB2-Ti-TiC1-x-TiB/TiB2-TiC1-x-TiB-Ti/TiB-TiC1-x-Ti/TiC1-x-Ti/Ti） characterized by the size and distribution of TiB phases.
