Description

The present study is a part of the development of 3 critical components for a hybrid electric/gas turbine engine. One of these components is a radial Si3N4 ceramic turbine wheel that requires a nondestructive inspection prior to experimental tests. The goal of the examination is to detect, size and localize flaws 80 μm or larger in the turbine wheel whose respective diameter and density are 100 mm and 3.22g/cm3. 3D X-ray cone beam tomography was selected by Renault as a nondestructive evaluation method capable of reaching this objective. The strong X-ray attenuation of such a ceramic part and the research of small size defects have driven the design of our system.
