Manufacturing process method for ceramic rotor type parts

The invention relates to a manufacturing process method for ceramic rotor type parts which are large in number of blades, complex in blade type structure and small in structure size and are made of high-temperature resisting hard and brittle ceramic. The manufacturing process method solves the problems that for existing ceramic rotor type parts, the manufacturing scrap rate is high, the manufacturing efficiency is low, and material performance cannot meet working demands. The manufacturing process method comprises the steps that the dimension of a part model is scaled up; a part blank is subjected to static pressure to be formed and prepared; a part is roughly machined through the milling process; the part is subjected to secondary high-temperature sintering to be compact; part blades are subjected to finish machining through the grinding process, and manufacturing is completed. According to the manufacturing process method, the machining efficiency is improved by 3-6 times, the scrap rate is decreased, and the quality reliability is improved; the tensile strength of the blades is up to 350 MPa, the blade profile precision is 0.08 mm, the dynamic unbalance value reaches 0.8 g.mm/Kg, and the surface roughness is smaller than 0.5 micrometer. By means of the method, a ceramic rotor large in number of blades and complex in blade profile structure is manufactured.
