Modern trends of using ceramic cores for aerospace and IGT sector

By Pavel Karafa

Abstract

The bachelor thesis deals with the manufacturing process and applications of ceramic cores for use in investment casting foundries. These ceramic cores find use extensively in the aerospace and energy industries for the production of turbine blades, or sometimes to create cavities in castings, which can’t be created by other methods. A separate task of ceramic cores described in the work is to create cooling cavities inside the body of the blade to improve the working process of the turbine. Work on the introduction briefly describes the casting using the lost wax method, which the turbine blades are produced, then the materials, separate process for producing ceramic cores, removing them from casting and default application of kernels
