Nano-structure alumina fiber composite ceramic material and preparation process thereof
The invention belongs to the technical field of functional ceramic material manufacturing, and relates to a nano-structure alumina fiber composite ceramic material and a preparation process thereof. The material is a nano-structure aluminum oxide-based composite ceramic material, and besides the aluminum oxide matrix material, the material also comprises a nano-scale aluminum oxide fiber reinforced phase, a nickel auxiliary binding phase and a zirconium oxide dispersion strengthening phase, wherein the nano-scale aluminum oxide fibers in the composite ceramic material are prepared through self-assembly by adopting an electrostatic spinning assisted gel sol method, and the composite ceramic material is prepared by adopting a hot pressing sintering method. The nano-structure alumina fiber composite ceramic material has outstanding high-temperature mechanical properties, thermal shock resistance and high-temperature oxidation resistance, and can be applied to equipment hot-end components.
