Abstract

Different regimes of interaction between tungsten nanopowders, produced by pulsed electric plasma spraying of wires, and air have been studied: passivation (slow-rate oxidation at room temperature), medium-rate oxidation by linear heating (15K/min) and combustion (fast-rate oxidation). A thermochemical oxidation diagram of tungsten nanopowders in air is proposed.
