Probing Through the Gas-Solid Interface with Thermal Waves: A Study of the Temperature Distribution in the Gas and in the Solid
Thermal wave nondestructive evaluation is one of the few NDE methods applicable to the characterization of ceramic and composite materials. As a near surface characterization technique, it has been shown to be useful for metals and semiconductors and has been developed for use with those materials. Limited work has been done with the technique on ceramics, with little effort to investigate the resulting fundamental differences which can occur in the case of insulating materials.
