Title

Characterization of nanoparticle layers deposited by wire explosions

Abstract
In a previous work [1], nanoparticle deposition of metal and metal compounds on a substrate layer by electric wire explosions was discussed. Nanoparticles are of wide interest in energetic material science because of their high reactivity and energy release. Mixtures made of metals and metal ox-ides show very fast conversion rates compared to micron-sized particle thermite mixtures. By using wire explosions, different materials can directly be deposited as nanoparticles onto a substrate. In this work, samples of deposited particles on a substrate were investigated by scanning electron microscopy (SEM), thermal analysis and X-ray diffraction. SEM measurements were used to determine particle size, homogeneity and layer thickness. Mixing different metals or metal compounds, the distribution of the different particles can be determined with this technique. Thermal analysis was done using thermogravimetric analysis (TGA). Data analysis provides insides into the oxide layer and oxidation degree. Furthermore, kinetic parameters for the oxidation of the metal particles can be derived. X-ray diffraction helps analyzing the deposited layer relating to composition and structure.
