Description

Thermal diffusivity which depends on the microstructural properties of the material, is very sensitive to the changes that take place in the material as a result of surface modification processes such as laser processing, case hardening and coating deposition. Considering this change in thermal diffusivity and the typical depths involved (a few micrometers to a couple of millimeters), photothermal techniques have proven to be a good non-destructive and non-contact method of profiling these subsurface inhomogeneities[l–3].
