Experiments on the gas protection of porous refractory materials from oxidation and erosion in plasma flows

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Summary

The possibility is demonstrated of counteracting high-temperature oxidation and erosion of the surface of refractory metals in plasma flows using protective gas films created by a blast through porous walls.

We evaluate the orders of magnitude of the relative protective gas consumptions for the required decrease. We describe the apparatus used to test the strength of porous refractory materials in plasma flows.
