在不同表面粗糙度的Be侧镀Ti/Cu中间层,采用热等静压技术将铍与CuCrZr合金进行扩散连接.通过AES、SEM(EDS)、室温剪切试验和XRD等分析其镀层形貌及成分、界面特性与相结构.结果表明:9 μm Ti、35 μm Cu镀层带征较为均匀,影响扩散连接强度的元素较少,采用双靶单侧镀复合膜的工艺有利于减少Ti镀层的氧化;界面剪切强度明显提高,最高可达243 MPa,Be表面粗糙度的不同对强度影响不明显;Be-Ti连接强度高,剪切断裂均发生在Cu镀层.

Ti and Cu were used as interlayer materials, and the diffusion bonding of Be/CuCrZr alloys were carried out onto Be side by hot isostatic pressing. The four Be samples had different surface roughness. The coating, interface behavior and microstructure of the diffusion bonded alloys were studied by AES, SEM (EDS), room-temperature shear test and XRD. The results show that the Ti coating band (9 μm thickness) and the Cu coating band (35 μm thickness) are homogeneous, and few harmful ingredients are observed. Dual-target and single-side coating technology is favorable to reduce the Ti-coating oxidation. Shearing strength of the Be/CuCrZr interface is increased significantly, with the highest up to 243 MPa. But effect of the different surface roughness on the shearing strength is not obvious. The bonding strength of Be-Ti is high, and all the shear fracture of the samples occurs in the Cu layer.
