アブストラクト
The paste of copper powder and the organic binder is buttered on a C/C composites plate and heated to 1200ºC for 20 min in the vacuum chamber. The copper-coated C/C composites are brazed to titanium alloys; commercially pure titanium rod. The brazing filler metals are Cusil-ABA® (Ag-Cu-Ti). The brazing conditions are 830ºC for 5 min in the vacuum. When the ply’s direction was perpendicular to the brazing interface and cupper coating was added on the C/C composites’ surface, the sound joints are obtained. This ply direction prevent the crack propagation caused by the CTE incompatibility, and the copper coating became the obstacle to the infiltration of the brazing filler into C/C composites.
