高速遠心成形法による超高強度アルミナの作製と高強度化機構の解明

抄録

High-Speed Centrifugal Compaction Process (HCP) is a variety of wet compacting method for fine ceramic powders by using huge centrifugal force of about 10, 000g. The compacting mechanism of the HCP differs from that of slip casting, a conventional wet compaction method, and therefore the HCP possesses a number of unique characteristics such as a higher compacting speed than pressure casting, wide applicability for net shape formation, as well as defect removing function. Because of homogeneous and flawless green microstructure, the HCP alumina shows a superior sinterabiliy and higher strength and hardness than most other alumina. These advantages can be emphasized with a higher centrifugal force.
