High temperature diffusion bonding has been applied for holding the both materials of the bushing together, which are outer steel materials and inner composite-sintered bushings.
The composite-sintered bushings are consisted of two different materials; outer steel material and inner porous sintered body respectively.
The composite-sintered bushing is made of steel outer skin with porous sintered body inside and the two (2) different materials are bonded together by high temperature diffusion bonding method.
The composite-sintered bushings are consisted of the two different materials; outer steel materials and inner porous sintered materials respectively.
