Abstract

Investment casting is one of the most critical technologies that produce can complex components used in aircraft engines (Litong et al. in Near net shape investment casting precision casting theory and practice. National Defense Industry Press, Beijing, 2007, [1]). The preparation of the ceramic shell is one of the essential processes in investment casting. The dimensional accuracy, surface roughness, and even internal quality of casts are all closely related to the ceramic shells (Jones and Yuan in J. Mater. Process. Technol. 135(2–3):258–265, 2003 [2]). In recent years, the structure of casting parts for aircraft engines has become more and more complex, and the surface quality requirements have become much higher, which demands higher standards for the performance of ceramic shells. How to further enrich and optimize the shell material system formulates a scientific and reasonable shell-making process. Besides, how to prepare a ceramic shell with excellent performance has become one of the critical points in the development of modern investment casting technology.
