Joining of High Strength Graphite with Silicon Resin and SiO2 Addition

摘要：

　　Joining of the high strength graphite to itself has been realized using silicon resin YR3370 with SiO2 powders as joining materials.The joining strength of the joints is strongly affected by adding SiO2 powders and joining temperature.Adding SiO2 filler can effectively reduce holes and cracks in the joining interlayer.Therefore it can enhance the joining strength.The maximum shearing strength of the joints is 21.1MPa,which is equal to 52.8% of the strength of the graphite substrate.This value is obtained at the joining temperature of 1200°C.The thickness of interlayer is about 25μm.The joining interlayer is uniform and dense,and the contact at the interfaces is good.
