Abstract
The aim of the study was to present the possibilities of X-ray computed tomography to evaluate the internal discontinuities in multilayer ceramic moulds for precision casting critical parts of aircraft engines.
Study for determination of internal discontinuities such as: porosity, micro-cracks and delamination at the ceramic moulds was carried out using the method of X-ray computed tomography. Using this method allowed to obtain a 3D virtual model of the ceramic form and, consequently, the measurement of porosity and thickness both the first layer and the constructional layer in the multilayer ceramic mould.
The results are presented possibilities of computer tomography as a tool for microanalysis 3D, identify internal discontinuities and measurement of geometrical size for assessing the quality of ceramic mold in relation to the research of its technological structure.
