Sintering enhanced by centrifugal force has been proposed. The application of centrifugal force during sintering enables to promote material transfer via plastic deformation, creep, and diffusion enhancement, resulting in higher density at lower temperature compared with conventional sintering. Further, this process is advantageous for diffusion bonding and thick film sintering, in which free of solid-contact contamination during the process is achieved. In terms of diffusion bonding, contact pressure more than several Mpa generated by the acceleration of 100 km/s2 can be applied for the specimens with a thickness of a few mm, which leads high tensile strength being identical with that of diffusion bonding via hot pressing. Hence, production of miniaturized ceramics-metal parts can be available by this process. Several demonstrated results of centrifugal sintering will be presented.
