Abstract

Hot centrifugal pressing has been proposed as a new processing technology of material integration. This process utilizes high centrifugal acceleration under various heating atmospheres. The potential of present process has been demonstrated in a variety of processes such as constrained sintering, diffusion bonding, and porous material structuring by means of its process selectivity. It was found that anisotropic shrinkage in centrifugal sintering was effective for suppressing crack formation in constrained sintering. Furthermore, sintering progress along rotational radius direction has been observed. Self-pressurized diffusion bonding has been also attempted, by which joining of ceramics with complex shapes has been successfully applied.
