Abstract
The paper presents the results of thermal studies for a sample of aluminum with nanoporous alumina using thermal imaging measurements. As a heating element, a carbon thread based on a viscose technical thread was used. On the base of results, it was established that local heating of the sample surface by the contact method using a linear heat source can be used in thermometry to determine the thermal conductivity of solid multicomponent dielectric materials.
