A ceramic tool with integrated temperature sensing and cutting functions and preparation method and application thereof. The ceramic tool comprises a ceramic matrix, a positive thermoelectric layer and a negative thermoelectric layer being provided on two surfaces of the ceramic matrix; the ceramic matrix being formed by sintering a first matrix material, a first binding agent and a first reinforcing phase, and the thermoelectric layer being formed by sintering of a thermoelectric material; the first matrix material comprises one or more of AlO, SiNand CBN; the first binding agent comprises one or more of Mo, Ni, Co, W and Cr; the first reinforcing phase comprises one or more of TiC, WC, SiC, MgO, CrO, TiOand ZrO; the thermoelectric material for the positive thermoelectric layer comprises ZrBand SiC; the thermoelectric material for the negative thermoelectric layer comprises ZrB, SiC, and graphite.

Ceramic tool with integrated temperature sensing and cutting functions, preparation method and application thereof

A crack self-healing functionally gradient material for ceramic cutting tools and a preparation method thereof. The material for ceramic cutting tools has a symmetrical gradient structure, and based on the percentage by mass, components of each layer include 50%-80% of Ti(C,N), 25%-5% of (W,Ti)C and 20%-0% of TiSi; contents of components of layers that are symmetrical relative to a central layer are the same and a thickness is symmetrically distributed; a content of Ti(C,N) gradually increases from the surface layer to the central layer, contents of (W,Ti)C and TiSigradually decrease by 5% from the surface layer to the central layer, and the contents of Ni and Mo gradually increase from the surface layer to the central layer.
