Electrophoretic Deposition of Al/CuO Energetic Materials and Their Heat Release Performance

摘要

In this study, Al/CuO energetic materials with high exothermic properties were prepared byelectrophoretic deposition of nano-Al and CuO microboxes on Ti sheets. The microstructure and phasecomposition of Al/CuO energetic materials were characterized by scanning electron microscopy (SEM)and X-ray diffraction (XRD). The electrophoretic deposition behavior of nano-Al and CuO microboxeswere systematically investigated, and the electrophoretic deposition process was controlled by diffusion.The differential scanning calorimetry results showed that the maximum heat released by Al/CuOenergetic material is 3049 J/g at an equivalent ratio of 3.0. The combustion properties of Al/CuOenergetic materials were tested by optical fiber spectra. When the equivalence ratio was 2.25, theintensity of the spectra of Al/CuO energetic materials were the strongest and the lowest color temperaturewas 2916 K. This work provides a reference for the preparation of highly exothermic Al/CuO energeticmaterials by electrophoretic deposition.
