Laser photoacoustic technique for ultrasonic surface acoustic wave velocity evaluation on porcelain
A laser photoacoustic technique has been developed to evaluate the surface acoustic wave (SAW) velocity of porcelain. A Q-switched Nd:YAG laser at 1064 nm was focused by a cylindrical lens to initiate broadband SAW impulses, which were detected by an optical fiber interferometer with high spatial resolution. Multiple near-field surface acoustic waves were observed on the sample surface at vario...
متن کاملLaser-ultrasonic surface wave dispersion measurements on surface-treated metals.
Surface acoustic wave (SAW) velocity spectroscopy has been long considered to be one of the leading candidates for nondestructive characterization of surface-treated metals because of its ability to probe the material properties at different penetration depths depending on the inspection frequency. We developed a high-precision laser-ultrasonic technique to study the feasibility of SAW dispersi...
متن کاملUltrasonic Velocity Measurements in Liquid Metals Using Acoustic Wave Guides
The ultrasound Doppler velocimetry (UDV) is an innovative and non-invasive method to determine the velocity in liquid flows. Main advantages are the ability to investigate flows of opaque liquids and to deliver complete velocity profiles in real-time [1,2]. Therefore, the intention to apply this measuring technique to liquid metal flows is obvious with respect to the situation that until today ...
متن کاملLaser Photoacoustic Technique for NDE
The technique of laser photoacoustic spectroscopy is applied to the studies of surface and sub-surface structures of solids in a nondestructive fashion. In the present case, special attention is focused on reaction-bonded Si N ceramics, which are used for the manufacturing of turbine blades. Good correlation is obtained betwee~ fhe observed photoacoustic signal and surface microstructures. In a...
متن کاملDiffraction correction for precision surface acoustic wave velocity measurements.
Surface wave dispersion measurements can be used to nondestructively characterize shot-peened, laser shock-peened, burnished, and otherwise surface-treated specimens. In recent years, there have been numerous efforts to separate the contribution of surface roughness from those of near-surface material variations, such as residual stress, texture, and increased dislocation density. As the accura...
