Paper Abstract

The problem of determining coating thickness and thermophysical characteristics using photothermal IR-radiometry is investigated theoretically and experimentally. The information about coating characteristics is contained in frequency dependence of surface temperature oscillation amplitude and phase. The optimization of thermal wave excitation modes (continuous wave and transient) has been done for different coating parameters. In experiments the characteristics of ceramic coatings on metal substrates were determined as well as their changes under technological processes.
