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.

Materials and Experimental details 2.1.
Materials CNTs (with 20–40 nm in outer diameter and >95% purity) were purchased from Shenzhen Nanotech Port Co., Ltd which were synthesized via chemical vapor deposition.

Geopolymeric materials are attractive because excellent mechanical properties and durability can be achieved [6].
Great interest also derives from the reduced energy requirement for the manufacture of new materials based on geopolymers.
The applications of geopolymer-based materials range within the fields of new ceramics, cements, matrices for hazardous waste stabilization, fire-resistant materials, asbestos-free materials and high-tech materials [1,9,10].
MATERIALS AND METHODS The three MSWI ash samples come from plants located in southern, central and northern Italy.
