| 摘 要： | 采用磁控溅射技术在TA15钛合金表面沉积Ti薄膜,在DD6单晶高温合金表面沉积Ni薄膜,以Ti,Ni薄膜作为中间层进行低温扩散焊研究.通过X射线衍射分析发现Ti,Ni薄膜均为多晶体结构.采用AFM分析发现,沉积薄膜后,TA15钛合金和DD6单晶基片的表面粗糙度均有所降低.以Ti,Ni薄膜作为中间层在800℃/20MPa/2h规范下实现了TA15钛合金和DD6单晶高温合金的异种材料低温扩散连接.通过扫描电镜和能谱分析表明,Ti,Ni两元素均扩散至另一母材界面,整个接头呈现分层组织,主要为Ti2Ni和TiNi相.

| Abstract: | Diffusion bonding of titanium alloy TA15 to superalloy DD6 was investigated at a lower temperature using Ti and Ni thin films as interlayer,which were deposited on the surfaces of TA15 and DD6 respectively by magnetron sputtering.X-ray diffraction analysis was carried out to test the crystal structure of films deposited on the substrate.The multicrystal structure was observed from both patterns of Ti and Ni films.The roughness of the substrate was examined by AFM.The results showed that the roughness of TA1... |
