In order to solve this shortcoming of alumina ceramics, researchers began to improve on the basis of the original alumina ceramic materials, thus obtaining superplastic alumina ceramics. This material not only overcomes the shortcomings of low plasticity of alumina ceramics, but also makes the material The scope of application has been further expanded. Superplastic alumina ceramics is a kind of Zr2O3 particles added to the raw materials of alumina ceramics, and when the Zr2O3 alumina particles are in a highly dispersed state and the crystals are fine particles, it will have good superplasticity and completely break through The defects of the original alumina ceramics are eliminated. It seems that superplastic alumina ceramics will replace ordinary alumina ceramics in various fields in the future, and with the development of the entire industry, computer technology and digital control technology will also promote the technological progress of the ceramic material industry. Efficiency, product quality and other aspects have also been significantly improved. At the same time, it will make domestic microcrystalline alumina ceramic products grow from scratch, the industrial scale will grow from small to large, and the product quality will increase from low to high, which will promote the gradual expansion of the entire industrial scale. Judging from the current application situation of alumina ceramics, the application range is getting wider and wider, and the dosage is getting bigger and bigger, and the prospect is bright. Regarding alumina ceramics, in addition to clarifying the reasons behind its discoloration, it is also necessary to master some basic principles of using it to make shaft cores to ensure that the obtained products meet the requirements and can be used normally.

Considering that the material is relatively special, it is necessary to be more cautious when designing the alumina ceramic shaft core to reduce unnecessary damage. The main content involved mainly includes the type, size and position of the installation parts, the fixing method of the parts, the nature, direction, size and distribution of the load; the type and size of the alumina ceramic bearing; the blank, manufacturing and processing of the alumina ceramic shaft. Assembly process, installation and transportation; deformation of the shaft and a series of factors. In a word, it must be designed according to the specific requirements of the alumina ceramic shaft, but on the premise of saving materials and reducing weight, try to use a cross-sectional shape with equal strength dimensions or a large section coefficient; And structural measures to improve the strength to further ensure the quality and performance of the product.
