Summary

Through thermal wave imaging, also known as photoacoustic microscopy, the surface and subsurface thermal properties of opaque coatings can be probed. These properties include thickness and bonding, both of which can affect the temperature variation at the surface. The capabilities and limitations of the gas cell approach are illustrated on CVD SiC coatings. Residual stress measurements on these coatings are summarized and the effect of exposure to high laser power densities is explored.
