Preparation method of aerostatic bearing with high structural uniformity
The invention discloses a preparation method of a high-structural-uniformity aerostatic bearing, which comprises the following steps: after rho aluminum oxide powder is pressed into tablets, gaps of powder particles are reduced, the whole volume space is limited, a confinement hydration reaction is carried out, gaps of original particles are filled with hydration products, the whole structure is homogenized step by step, and high-temperature phase change is carried out, so that the high-structural-uniformity aerostatic bearing is obtained. The material is converted into an aerostatic bearing material with high structural uniformity. The problem that the structure uniformity of the aerostatic bearing is difficult to realize due to non-uniform ceramic powder particles when ceramic powder is conventionally used as a raw material is solved, and the performance of the aerostatic bearing is improved by realizing the homogenization of the whole ceramic structure in the technological process.
本发明公布了一种高结构均匀性气体静压轴承的制备方法，该方法利用ρ氧化铝粉末压片后，缩小粉末颗粒间隙，整体体积空间受到限制，再经过限域水合反应，水化产物先填充原颗粒间隙，再逐步完成整体结构的均匀化，然后经过高温相变，转化为高结构均匀性的气体静压轴承材料。解决了常规以陶瓷粉体为原料，由于陶瓷粉体颗粒不均，难以实现气体静压轴承结构均匀的问题，通过工艺过程中实现整体陶瓷结构的均匀化，使得气体静压轴承性能得到提升。
