Ceramic fabrication R D
This project is separated into three tasks. The first task is a design and modelling effort to be carried out by MSE, Inc. The purpose of this task is to develop and analyze designs for various cohesive ceramic fabrication (CCF) components, principally an MHD electrode for strategic defense initiative (SDI) applications. A high stress, low cost, ceramic component is to be selected, designed and, if possible, analyzed. The final design for the MHD electrode comprised a layered structure of molybdenum disilicide graded with quartz glass. The design demonstrates the fabrication capabilities of the CCF process. The high stress component was targeted at armor applications and will be thick alumina plate. Silicon carbide reinforcement of the alumina will be explored. Task 2 is directed at establishing a mechanical properties data base for monolithic and laminated alumina fabricated using the CCF process. Task 3 involved production of a solid oxide fuel cell model electrode; however, work ceased when it became apparent that successful integration of the electrode modules would require additional time. Currently, work is principally focused on the production of thick CCF alumina plates; three test plates were ballistically tested and showed a very satisfactory performance. Silicon carbide reinforcement of the CCF alumina is being explored. Effort on the CCF processing of molybdenum disilicide (a nonoxide material) continued at a reduced level. Sinter aids were explored, and densities of 87% theoretical density on pressureless sintered dry pressed pellets were achieved. 1 ref., 9 figs., 4 tabs.
