The applications of high performance materials in the aerospace and in the automotive technology in the next years need to develop new vibration study, nondestructive testing, predictive maintenance and industrial control methods.The Laser Scanning Vibrometry and Holographic Interferometry methods of vibration study and nondestructive testing by modal analysis are described. The Laser Scanning Vibrometer PSV 400 is made by Polytec GmbH and the PSV software reconstructs the 3D model of the measured micro-deformation of the object. The holographic laser system HLS-3 from Lumonics Inc. has 100 MW ruby laser peak power and 30 ns pulse width.Using mechanical excitation to induce a measurable vibration, the Laser Scanning Vibrometry and Holographic Interferometry modal analysis measurements show up the vibrational signatures and the damaged areas of the objects made by high performance materials - polymers, composites.

Chemical Synthesis Route

The surface of Ti6Al4V alloys was activated by a selective laser microstructuring and subsequent sintering of hydroxyapatite (HAp) nanopowders into the generated structures. For structuring, a novel q-switched CO2laser with pulse durations of about 600 ns and a peak power of up to 60 kW was used. This laser system provides defined blind holes and channel-like geometries with structural sizes in the range of 100-500 μm. The influence of different process gases (Ar, O2, N2) on the formation of titanium oxide (TiO2) and titanium nitride (TiN) interfaces during laser structuring was investigated by GDEOS. HAp nanopowders prepared by a wet-chemical synthesis route were subsequently sintered into the generated structures using a CO2laser with continuous radiation intensities up to 2·102W/cm2. The homogeneously sintered structures consist of HAp as the major phase and minor amounts of tricaliumphosphate (TCP) and tetracalciumphophate (TTCP). The formation of TCP and TTCP during laser sintering can be minimized by adjusting sintering parameters (time, laser intensity) and by applying additional process gases (O2, Ar).
