Photothermocapillary Method for the Nondestructive Testing of Solid Materials and Thin Coatings
The photothermocapillary (PTC) effect is a deformation of the free surface of a thin liquid layer on a solid material that is caused by the dependence of the coefficient of surface tension on temperature. The PTC effect is highly sensitive to variations in the thermal conductivity of solids, and thi...
