Abstract:
This article presents research results on modern ceramic materials used for the manufacturing of critical elements in aircraft engine hot zones, by using investment casting technology. Investment casting using multi-layered ceramic moulds is commonly used in the production of aircraft components. This technology allows precise reproduction of geometrically complex spatial shapes. The quality requirements that the final product must meet, which are extremely and increasingly rigorous, necessitate a permanent solution for technologically complex problems related to castings defects that are dependent on the ceramic mould's technological quality. Prevention of casting defects is accomplished by optimizing the parameters of the metallurgical process, and by improving structural and technological construction of the mould. On the other hand, to limit the defects coming from the mould's technological quality, one should correctly select technical and auxiliary materials for constructing self-supporting ceramic moulds and the parameters of the manufacturing process.
