Abstract
A new approach is expected for heat resisting metal joints with inorganic adhesive. In this study, the mechanical characterization of the inorganic adhesive and the strength evaluation of metal joints are composed of an experimental procedure including static test for single lap joints bonded with inorganic adhesives. The inorganic adhesive can be cured at 150℃ and the maximum temperature resistance proposed is up to 1200℃. Tensile shear test for the joints with nickel adherend are performed at elevated temperature up to 400℃. Effect of material property, overlap length and thickness of adherend on the joint strength is discussed with stress analysis for corresponding joint models by a Finite Element Method. It is important to make sure which the fracture is occurred, in adhesive layer or at interface between adhesive and adherend. Therefore, deformation and fracture behavior of the adhesive layer is investigated microscopically with SEM photographs of the fracture surface.
