摘要： 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.

摘要： A single-crystal β-Ga2O3 MSM detector and a preparation method thereof, comprising: machining grooves on a single-crystal β-Ga2O3 substrate using a laser-assisted waterjet machining technique to form a 3D shape; wet etching the machined single-crystal β-Ga2O3 substrate using an HF solution to remove machining damage; performing Au evaporation on a surface of the single-crystal β-Ga2O3 substrate after processing, coating an Au thin film on the surface of the single-crystal β-Ga2O3 substrate; and grinding the surface of the single-crystal β-Ga2O3 substrate after evaporation to remove the Au thin film on an undressed surface and retain the Au thin film in the grooves, and then obtaining the single-crystal β-Ga2O3 MSM detector.
