Development of metrological NDE methods for microturbine ceramic components
In this work, X-ray computed tomographic imaging technology with high spatial resolution has been explored for metrological applications to Si{sub 3}N{sub 4} ceramic turbine wheels. X-ray computed tomography (XCT) data were acquired by a charge-coupled device detector coupled to an image intensifier. Cone-beam XCT reconstruction algorithms were used to allow full-volume data acquisition from the turbine wheels. Special software was developed so that edge detection and complex blade contours could be determined from the XCT data. The feasibility of using the XCT for dimensional analyses was compared with that of a coordinate-measuring machine. Details of the XCT system, data acquisition, and dimensional comparisons will be presented.
