Abstract

A novel mid-infrared transmission imaging (MIR-TI) technique for the nondestructive, optical inspection of yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) components is described. This technique was designed specifically for the detection of flaws and cracks within the bulk of the ceramic component. The MIR-TI technique exploits a transparency window in Y-TZP from 3 to 7 µm; at shorter wavelengths the material is highly scattering, while at longer wavelengths it is absorbing. We demonstrate that using this technique it is possible to detect micrometer-scale flaws at depths of up to 6 mm. © 2009 The American Ceramic Society.
