Abstract

The invention relates to a method for quickly forming and manufacturing a ceramic core, which comprises the following steps of: uniformly mixing a low temperature reinforcer and ceramic powder and then performing SLS quick forming on the mixture; performing pretreatment on the obtained ceramic core blank; removing the low temperature reinforcer from the ceramic core blank, and soaking the blank into a high temperature adhesive for presintering and degreasing; and sintering at a high temperature to obtain a final integral ceramic core product. The method has the advantages that: (1) the ceramic core of a hollow radiating blade with complex section can be integrally manufactured; (2) a mold is avoided, flexibility is high, and various ceramic workpieces can be quickly formed; and (3) process flow is simple and production efficiency is high. The ceramic core of the hollow radiating blade which is manufactured by the method has the advantages of high heat conductivity, light mass, accurate size and the like.

Description

technical field

[0001] The invention relates to the technical field of rapid prototyping, in particular to a rapid prototyping manufacturing method of a ceramic core, which is especially suitable for the rapid prototyping of precision casting ceramic cores of turbine hollow blades. Background technique

[0002] Turbine hollow blades are the core components of high-performance power generation equipment and aero-engines. They are listed as the first key parts because they are located in the parts with the highest temperature, the most complex stress and the harshest environment. Sir Jhon Rose, CEO of the British Roll-Royce company, called it The "jewel in the crown" of manufacturing. The application of vortex cooling technology and film cooling technology makes the internal structure of the blade more complicated. At present, the manufacturing of turbine blades mainly adopts the investment casting process. The prior art process is complex, the product development cycle is l...
