Abstract

This paper presents the results of an investigation into a simple technique developed primarily for evaluating surface coating effectiveness for the absorption on a non-uniform laser radiation heat flux.
Results of an analysis suggest that if the transducer sensor is designed appropriately, and the experimental data analyzed in a particular manner, the temperature-time history of the transducer need be measured at only a single arbitrary location. These conclusions are also supported by experimental measurements for laser radiation absorption at a wavelength of 10.6 µm for polished copper, polished steel, and for a manganese-phosphate coating on a steel substrate. The absorptances measured for the polished copper and steel agree well with other experimental data in the literature.
