Second joint test of a US electrode system in the USSR U-02 facility. Final report
The second (Phase II) joint U.S.-U.S.S.R. test of U.S. electrode materials was carried out in Moscow between September 21 and September 27, 1976 in the Soviet U-02 MHD Facility. The test procedure followed closely a predetermined work plan designed to test five different electrode materials, different lead-out and attachments, and the cathode and anode electrode walls under MHD operation conditions. Extensive pre- and post-test materials characterizations were made to determine the effect of the MHD environment on the electrodes and insulators. Measurements included: thermal diffusivity, thermal expansion, chemical composition, microstructure, electrical conductivity, phase composition, closed and open porosity, pore size distribution and radiography. Results indicated that there was extensive attack by the seed on the cathode wall resulting in chemical reactions and phase changes of the electrode materials.
