Abstract

In this paper, the features and main nuances of electrophoretic deposition of energetic nanoscale powder materials based on Al and CuOx were investigated and formulated. We have successfully demonstrated the advantage of using suspension non-stop ultrasonic mixing and horizontal electrode placement during deposition. The possibility of local deposition of energetic materials on an electrically conductive topological pattern was shown. The influence of the mass of the deposited material on the behavior of the wave combustion process of a locally formed energetic material was investigated. This study provides guidance for the multiobjective optimization and increasing the reproducibility of the local electrophoretic deposition process of energetic materials. The results indicate that Al-CuO_x mixture can be integrated into microenergy systems as a material with excellent specific energy characteristics and high combustion rate.
