چکیده انگلیسی
A novel method for the in suit synthesis and bonding of Cu to W-Cu composite was developed by combining combustion synthesis with centrifugal infiltration. Highly exothermic combustion reaction in Al-CuO system was utilized to realize high temperature and produce molten products. The application of high gravity field of 1000G resulted in a rapidly phase separation of Cu melt and infiltration of W loosen powder. Composition and microstructure showed a layered variation along high gravity direction. Cu was bonded to W-Cu composite to form a Cu/W-Cu integral material. Columnar grain microstructure was observed on Cu layer due to a fast cooling rate produced along high gravity direction. Pores were found concentrated at the interface between Cu and W-Cu layer. The evolution of thermal conductivity and hardness along high gravity direction were investigated.
