Interaction of Porous Electrode Materials with an Air Plasma Flow during the Blowing Through of Protective Gases

Abstract

The problem of creating reliable materials for the electrodes of open cycle MHD generators is still incompletely resolved. The accumulation of experimental data on the interaction of refractory electrode materials with aggressive flows is one of the pressing problems in seeking the necessary compositions, technology of separation and means of protection against electrode destruction. Carbides and borides of transition metals from groups IV-VI of the periodic system, having high melting points, high hardness, high temperature- strength, wear resistance, high thermal and electrical conductivity, are of considerable practical interest in high temperature technology, in particular when they are used as the electrode materials in MHD equipment. The work studies the behavior of niobium and titanium carbides, and zirconium boride in a flow of air plasma.
