| Zusammenfassung | With the application of high-aspect-ratio microstructures (HARMS) in various fields of industries, some novel non-destructive detection technologies have been developed in the past decades to measure the geometry, topography or roughness inside the HARMS. Among the above technologies, the Profilscanner with the slender piezoresistive microprobe has proved its ability to perform traceable roughness measurements inside small holes with diameters down to 50 µm. Chang of the inner surfaces of HARMS can occur during the utilizations such as the fuel deposit in the inject nozzles and it results in decreased performance of the structures. To analyze the structure performance, it is not only demanded to measure the inner topography, but also to characterize the material mechanical properties. The material mechanical properties measured from small length scales specimens can be deviated from that of bulk specimens. Contact Resonance (CR) method can quantitatively measure the material mechanical properties of small length scales specimens through analyzing the resonant frequencies of the cantilever with analytical models. Here the CR technology will be applied in Profilscanner to detect the material mechanical properties in small holes. |
