A new joining process assisted by centrifugal acceleration is proposed. The process requires no pressurizing media, and enables diffusion bonding of parts with complex shapes, as demonstrated in this paper. As an ad- ditional merit, contamination from media can be basically avoided. These features derive from an unique pressing method that uses high centrifugal force of up to kara 〜90 km/s^2, enhancing the joining strength of interfaces. Trial results indicate a tensile strength for Al_2O_3/Al/stainless steel joints equivalent to that of conventional diffusion bonded joints and double the adhesion strength of Cu thick film on quartz glass as compared to conventional screen printing.
