Abstract
A ceramic casing structural part, including a ceramic casing and a frame, where the ceramic casing includes a ceramic flat plate and a ceramic projection that is partially embedded in the ceramic flat plate, the frame abuts the ceramic flat plate along a thickness direction of the ceramic flat plate by using the ceramic projection, an upper surface and a lower surface of the frame are respectively level with an upper surface and a lower surface of the ceramic casing. The frame can protect an edge of the ceramic casing from a direct collision with another object, and the ceramic projection can increase a binding force between the ceramic casing and the frame, thereby improving an overall drop-resistant capability of the ceramic casing structural part in the present invention.
Claims11
A ceramic casing structural part, comprising:
- a ceramic casing;
- and
- a frame,
- wherein the ceramic casing comprises a ceramic flat plate and a ceramic projection that is partially embedded in the ceramic flat plate, the frame abuts the ceramic flat plate along a thickness direction of the ceramic flat plate by using the ceramic projection, an upper surface and a lower surface of the frame are respectively level with an upper surface and a lower surface of the ceramic casing, a material of the ceramic flat plate is a dense ceramic material with a density higher than 90%, a material of the ceramic projection is a porous ceramic material, and a material of the frame is an alloy, a metal-base composite material, or plastic.
A method for preparing a ceramic casing structural part, comprising:
- taking ceramic powder;
- performing ball-milling to prepare dense ceramic slurry;
- taking more ceramic powder, adding a pore-forming agent, and performing ball-milling to prepare porous ceramic slurry;
- separately drying and then graining the dense ceramic slurry and the porous ceramic slurry;
- filling them respectively into a groove in a ceramic casing die corresponding to a ceramic flat plate and a groove in the ceramic casing die corresponding to a ceramic projection to mold them into a ceramic embryo;
- sintering the obtained ceramic embryo to prepare a ceramic casing, wherein the ceramic casing comprises a ceramic flat plate of a dense ceramic material with a density higher than 90% and a ceramic projection of a porous ceramic material, wherein the ceramic projection is partially embedded in the ceramic flat plate;
- and
