摘要:

在铍上用物理气相沉积(PVD)镀上10μmTi 和10μmCu,再添加不同厚度的(分别为0.00mm、0.25mm、 0.50mm、0.75mm、1.00mm)无氧铜作为中间过渡层,与CuCrZr/316L(N)复合板基座铜合金侧通过热等静压连接。采用光学显微镜、扫描电镜(SEM)与电子探针(EPMA)、X 射线衍射仪(XRD)、剪切试验等方法确定了界面组织与性能。试验结果表明:各厚度无氧铜模块连接成功,界面无裂纹、空洞等缺陷,钛铜间出现三层明显的反应层,分别为CuTi2、CuTi 以及Cu4Ti。添加无氧铜厚度越大,剪切强度越大。

Abstract:

Beryllium (PVD coated on Ti, 10μm, Cu, 10μm), different thickness of oxygen-free cooper (OFC) sheets as transitionlayer and CuCrZr/316L(N) explosive bi-metallic plates are bonded by hot isostatic pressing (HIP), optical microscope, scanning electron microscope(SEM), Electron Probe Micro-analyzer(EPMA), X-ray diffraction( XRD), shearing tests are used to verify the diffusion bonding performance. Results turn out to be all kinds of mock-ups successfully bonded, no any cracks have been found in the diffusion bonding interface, three different kinds of diffusion layers are found between titanium and copper which are CuTi2、CuTi and Cu4Ti, respectively. The thicker of the OFC layer is, the better the shearing testing performance is.

Key words: Be-Cu bonding, Hot isostatic pressing, Shearing strength, Residual stress
