Efforts during the July to September 1977 quarter were directed toward the design, fabrication and evaluation of ceramic MHD electrodes for both clean fuel and coal fired environments. Laboratory screening tests continued to evaluate the electrochemical corrosion encountered for coal-fired conditions. A series of tests were conducted on MAFF in an eastern synthetic slag which resulted in identification of the degradation mechanisms for anodes and cathodes. Torch testing was completed to evaluate several attachment techniques and to determine the resistance of LA/sub 0/./sub 95/Mg/sub 0/./sub 05/CrO/sub 3/ to thermal shock. Clean-firing tests of a cold copper electrode test assembly and a hot LaCrO/sub 3/ electrode test assembly were completed in WESTF. In addition installaton, checkout and initial operation with oxygen was completed. Primary emphasis was put on the design and analysis of electrode systems included in the Proof Test Series for the U-02 Phase III Module. Assembly of the initial proof test assembly is underway. This test is scheduled for October 1977. Development and fabrication activities for the electrodes to be incorporated into the subsequent proof tests is proceeding.
