Abstract— The changes in the surface layer of aluminum particles treated with V2O5 • nH2O hydrogel were studied by ellipsometry and raster electron microscopy methods. It was shown that at 0.8 wt.% content of metallic vanadium in the modified powder, the particle surface layer has a well developed relief, and a high degree of impregnation is achieved. The values of the thickness of this layer measured by different methods were compared, and the obtained deviations were analyzed.
Keywords— aluminum powder, surface modification, vanadium pentoxide, microscopy, ellipsometry.
