The objective of this program is to develop economic MHD electrode and insulator designs that will sustain long term open-cycle MHD generator operations. Emphasis within this program is directed towards the understanding and development of cold metallic electrodes which are alternatives to the continued use of platinum as an anode clad material. Results of laboratory screening tests are presented for materials previously tested by AVCO and for other available commercial alloys. Results of anode arc tests are compared to observations from electrodes tested in an MHD generator. Laboratory electrochemical corrosion testing has been conducted at two temperatures in molten salts. Initial results from these tests are reported and analyzed. Fabrication of two commercial alloys with 7% platinum included was accomplished and electrochemical testing performed. A superior high temperature performance was noted. WESTF facility checkout and activation operations have been completed and facrication of the base copper electrode test section is reported. Detailed engineering and test planning activities in support of WESTF tests are reported.
