Development of new forming method-pressureless powder packing forming method and its applications

摘要

In order to overcome the demerit of conventional forming method, new forming method, pressureless powder packing forming method, as investigated. This technique involves powder packing by vibration, followed by the infiltration of binder solution, to fabricated the green body. Various AL_2O_3 and SiC powders were used as starting material and the characteristics of green bodies and sintered Specimens were investigated, and several composites were fabricated by infiltration process. As a Results, it was found that it was possible to produce the homogeneous ceramic bodies of complex shape And fabricate ceramic composites of near net shape.
