Abstract: A method for preparing a shell-bionic ceramic tool and a shell-bionic ceramic tool, wherein the shell-bionic ceramic tool includes alternating stacks of ceramic powders with different components, pressing a ceramic green body using a cold briquetting method, carrying out pre-pressing once using a graphite indenter on a working surface thereof after each layer of the ceramic powder being loaded, and pressing a last layer using a graphite rod, and then pressing a whole ceramic green body with a certain pressure to promote a bonding of the layers of ceramic powder, which in turn gives a complex shape to an interface between the layers, increases a bonding area between the layers, and plays the role of hindering crack expansion, extending the crack expansion path, and improving the bonding strength of the interface; after then, hot-pressed sintering is used to densify the ceramic green body to obtain the shell-bionic ceramic tool.

Abstract: A self-rotation cleaning device has outer and inner housings, a workpiece rotating system, an ultrasonic cleaning system and a fluid perfusion system. The inner housing is in the outer housing in a horizontal direction. A cylindrical cavity is inside the inner housing. One end of the inner housing has a sealing cover detachably connected thereto, and the other end is closed. The workpiece rotating system is in the cavity for fixing a member to be cleaned, and realizes self-rotation of the member. The ultrasonic cleaning system supplies mechanical energy to the cleaning liquid in the inner housing to generate bubbles therein. The bubbles remove residual resin attached to the cleaned member surface by continuous vibration and burst. The fluid perfusion system provides self-rotation power for the cleaned member, and continuously delivers the cleaning liquid to the inside of the cleaned member, and the cleaning liquid is carried out after cleaning.

Abstract: 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.
