Crack self-healing functionally gradient material for ceramic cutting tools and preparation method 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(C7,N3), 25%-5% of (W7,Ti3)C and 20%-0% of TiSi2; 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(C7,N3) gradually increases from the surface layer to the central layer, contents of (W7,Ti3)C and TiSi2 gradually 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.
