Abstract
An optimal content of silver doped vanadium pentoxide nanofillers (Ag-V2O5 NFs) was envisaged for reinforcement in Ti-based surfaces for boosting up the operational performance of high-supersonic and hypersonic missiles. Bar-shaped Ag-V2O5 NFs developed at 1, 3, and 5 % doping contents synthesized via microwave-assisted chemical solution technique were investigated for morphological, crystallographic, structural, and compositional properties by employing FESEM, XRD, Raman, and FTIR spectroscopy. Owing to their solubility differences, a blend of orthorhombic α- and β-phases were identified as spectral fingerprints specific to the developed Ag-embedded vanadium oxide crystalline structures. The Williamson-Hall method estimated the average crystallite size of α-Ag3-VO4 and β-Ag0.35-V2O5 phase NFs as 31.4 and 29.9 nm, respectively. The best results of the developed Ag-V2O5 NFs for the surface material transpired for the monoclinic metastable β-Ag0.333-V2O5 phase at optimal 3 % doping content with 13.7 nm average crystallite size, 0.35 % lattice strain, and 4.113 g/cm3 mass density.
