Development, testing and evaluation of MHD materials and component designs. Quarterly report, April--June 30, 1978
Efforts were directed towards the evaluation of MHD electrodes for both clean and coal fired environments. Electrochemical screening tests of electrode and interelectrode insulator materials has continued in simulated eastern and western liquid slags. A laboratory test rig is operational to investigate the arc damage experienced by cold wall anode materials. Preliminary tests have been run on copper (bare and plated) and Inconel. Results to date support continued use of this laboratory screening test to rank materials and fabrication techniques. WESTF modifications for slagging operation were completed and a series of facility checkout runs using a dummy test section are in progress. Difficulties have been encountered in these runs requiring minor modification of the exit piping to preclude plugging due to slag buildup. The U-02 Phase III Module was assembled, delivered to the U.S.S.R. in April and tested in the U-02 Facility in May. The duration of the U-02 Phase III Test was 132 hours, 100 of which were under full MHD conditions. The electrode walls were returned to the U.S. and sectioned; post-test material characterization efforts have been initiated. While material degradation was noted, the test was successful in that the electrode systems functioned for the duration of the test without loss of attachments.
