MHD electrode development. Quarterly report, January-March 31, 1980
Progress on the program to develop improved electrode designs for open-cycle coal-fired MHD generators is reported. Platinum capped anodes and iron cathodes, operating in the slagging hot mode, have been included in WESTF Test 43. Further results of bonding studies in support of this test are presented. The results of thermal diffusivity measurements made by Battelle Pacific Northwest Laboratory (BPNL) of super-hot hafnia electrode and indium oxide current leadout materials are reported. Laboratory electrochemical corrosion tests have been continued. Results reported herein indicate that Fe/sub 3/O/sub 4/ additions are effective in reducing polarization in Western slags. In comparison with cobalt oxide additions, the Fe/sub 3/O/sub 4/ addition provides significant cost advantages. During this period, significant WESTF operations included WESTF Test 47, 42, 43 and 49. This test sequence included tests of: slagging cold metallics in the MTS II test section; hafnia and zirconia coupons in the WESTF test section (non-slagging super-hot conditions); platinum/iron run under slagging hot conditions in the WESTF test section, and, a test of the 0.5 SrZrO/sub 3/.0.5 (Sr /sub 25/La /sub 75/ FeO/sub 3/) material in the non-slagging super-hot mode in the MTS II test section. Upon completion of WESTF Test 49, facility test operations were suspended and modifications of the facility, to support the addition of a 3 Tesla magnet, initiated. The status of design, procurement and modification activities is presented.
