Abstract

The mechanism of the interaction of a composite material conzhaschego tungsten, copper, lead, with atmospheric oxygen at temperatures up to 1000 °С at the surface is heated using solar energy concentrator. Determined by the multistage oxidation process. Shows the probability of the formation of surface metal tungstates, which block the surface of the composite and limit the further course of (he process of destruction com/positives.
