Аннотация

The passivation, oxidation and combustion of tungsten nanopowders (NP) (as ∼ 100 nm), produced by an electrical explosion of wires (WEE) method, has been studied in air medium. The phase transformation for W nanopowders under air-oxidation was investigated. The oxidation process and an analysis of passivated powders were studied by FESEM, EDS, XPS, XRD, TEM, DTA-TGA and size distribution analysis was also observed by a video camera. After the comprehensive testing of passivated, oxidized and burned powders, a chemical process of oxidation of W nanoparticles was suggested.
