In　present　study,　homogeneous　joint　of　ZrCx　ceramic　was　achieved　by　diffusion　bonding　using　Ti/Ta/Ti　as　the　interlayer.　The　effect　of　bonding　temperature　and　time　on　the　microstructure　and　mechanical　property　of　the　joints　was　uncovered.　The　homogeneous　joints　can　be　formed　at　1400　degrees　C　for　2　h　and　at　1500　degrees　C　for　1　h,　respectively.　The　Ti/Ta/Ti　interlayer　prefers　to　form　Ti-Ta　solid　solutions　rather　than　to　form　carbides　with　ZrCx　ceramic　during　the　bonding　process,　which　is　more　readily　to　be　dissolved　with　the　base　ceramic,　thus　contributing　to　the　formation　of　the　homogeneous　joints.　The　mechanical　property　of　the　homogeneous　joints　can　be　comparable　to　that　of　the　base　ceramics　due　to　the　similar　composition　of　the　joint　with　the　base　ceramics.　The　unique　microstructure　feature　and　mechanical　property　of　the　homogeneous　joints　illustrate　the　great　potential　of　our　method　for　joining　transition　metal　carbides.
