Abstract

The fundamental possibility of identifying a mathematical model of heat transfer in thin ceramic coatings enriched with SiO2 nanoparticles has been investigated. Thermal tests of samples with different nanoparticle contents (0–1.0%) have been performed to establish the thermophysical properties (thermal conductivity and heat capacity) of the coatings using the inverse heat transfer techniques, in particular, the iterative regularization method. The results obtained make it possible to evaluate the efficiency of the proposed approach to studying these coatings for increasing the durability of thermal protection materials used in aerospace engineering under extreme conditions.
