Abstract
Within the framework of the program promoted by ENEA (Italian Agency for Energy, New Technologies and the Environment) on magnetonydrodynamic (MHD) Systems, ENEA, Ansaldo Ricerche and Temav started a research and development activity on ceramic materials for the electrodes of the MHD channel at high temperature. The design input for the ceramic material used in the plasma was zirconia doped by yttria or ceria, and two different kinds of junctions for the electrode assembly (sintered body brazing or powder plasma spraying). The hot electrodes will be tested on a 1 MV MIDA facility. The first step of this activity was the development and set up of the following processes: powder production, sintered bodies manufacturing, plasma spraying, electrode assembly. The material was characterized by microstructural, electrical, thermomechanical and NDE points of view. In the first phase of activities, 50 kg of powder, 300 sintered components for characterization and for the electrodes, and 50 assembled electrodes were produced.
