“…Changing the deposition modes makes it possible to control the thickness of the layers of materials -from hundreds of nanometers to tens of microns. Until now, this approach has been successfully used many times for the formation and study of various powder thermite materials [31][32][33][34][35][36][37] and seems promising for obtaining answers to the previously indicated questions in the framework of this work. It is also important that the formed layer is sufficiently dense; that is, pressing is not required for conventional powders.…”

We investigated the reactions in composite thermite layers consisting of Al, CuO, and Cu 2 O nanoparticles formed by electrophoretic deposition on a titanium substrate. The composition determined the reaction propagation rates and heat effects in oxygen and oxygen-free atmospheres. It was found that a stable self-propagating exothermic reaction in the aluminum-copper oxide layer takes place in the range of 50-80 wt.% of Al. The maximum values of the measured heat effects also fell in this range.At the same time, the calculation following the stoichiometry of the reaction shows the optimal range of the Al amount is 10-20 wt.%. To explain this fact, we proposed a model based on calculating the probability of contact between Al and CuO particles depending on the average particle size and their concentration. The model is based on the calculation of solid angles, which means that the exact value of the contact area does not play a decisive role in this case.
