| titleOfInvention | Manufacturing method and application of honeycomb blind hole toughened zirconia ceramic shell |
| abstract | The invention discloses a method for manufacturing a honeycomb blind hole toughened zirconia ceramic shell and its application. In this method, the green body is sintered at a temperature lower than the firing temperature of ceramics so that the particles are partially adhered to have a certain strength, and the density is only 85% to 95% of the theoretical density. After the blind hole is sintered and compacted again, the organic polymer plastic material such as epoxy resin or silica gel is filled and cured in the blind hole. This scheme adopts sintering processing lower than the sintering temperature, which has better machinability than the injection molded body, and has higher processing efficiency and cost advantages than the sintered parts. Part of the impact energy of the drop is absorbed in the ceramic shell, thereby improving the fracture toughness of the ceramic shell. On the other hand, this solution can effectively reduce the weight of the shell, which is beneficial to the thinning of electronic products, and can be used to prepare consumer electronic shells such as watch shells, mobile phone shells, and tablet shells. |
