Abstract

The invention provides a novel high-purity super-tough zirconia composite ceramic gear and a preparation method thereof. The invention provides the high-purity super-tough zirconia composite ceramic gear prepared from high purity zirconia and other oxides through compounding and the preparation method thereof. The nanometer high purity composite zirconia powder, a residual-free binder, a residual-free surfactant, a residual-free lubrication agent and a residual-free plasticizer are mixed, then the mixture is subjected to granulation, the granules are added into an injection molding machine and are subjected to injection molding, and the molded granules are subjected to gum dumping and sintering treatment so that the high-purity super-tough zirconia composite ceramic gear is obtained. The high-purity super-tough zirconia composite ceramic gear has the advantages of high purity, high toughness, high strength, simple preparation process and equipment, low cost, high yield, low energy consumption and high production efficiency and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of material preparation technology, and in particular relates to a high-purity super-tough zirconia composite ceramic gear and a preparation method thereof. Background technique [0002] With the gradual development of electronic information and high-end mechanical systems, injection molded products have been applied in the fields of medical treatment, information, automotive engineering, automation, environment and safety, and daily life, with an annual growth rate of 20%. Compared with the silicon-based material component forming process widely used in the mechanical field, injection molding technology has low manufacturing cost, short production cycle, simple forming process, easy guarantee of component quality, and easy realization of automation and mass production. Ceramic parts for industrial special purposes are difficult to be formed by ordinary processing methods. Therefore, injection molding techno...
