    摘要:

    采用磁控溅射沉积40μm铜膜作为中间层,分别在950℃、980℃和1050℃下通过热等静压(HIP)焊接技术制备了国际热核聚变实验堆(ITER)计划W/CuCrZr偏滤器部件焊接模块,以考察温度对磁控溅射沉积40μm铜膜作为中间层W/CuCrZr偏滤器部件焊接质量的影响。通过扫描电子显微镜(SEM)和X射线能谱(EDS)分析焊接界面的形貌和成分,利用超声波无损探伤(NDT)仪对焊接界面缺陷进行了检测,利用力学拉伸试验机考察了焊接界面的结合强度和CuCrZr合金的力学性能。结果表明:磁控溅射法沉积40μm铜膜作为中间层,可以有效的提高HIP焊接界面质量。特别是在980℃时,所制备的焊接模块能够满足ITER计划对于偏滤器部件连接性能的要求。

    Abstract:

    The nternational thermonuclear experimental reactor (ITER) project W-Cu divertor component model was made by hot isostatic pressing (HIP) diffusion welding method under three HIP diffusion welding processes with the temperature of 950℃, 980℃ and 1050℃ respectively,and the model is studied by analyzing a module using the magnetron sputtering method to deposit a 40μm-thick copper coating as the interlayer. This paper aims to study effect of the magnetron sputtering method to deposit a 40μm-thick copper coating as the interlayer of W-Cu divertor component model properties. The morphology and composition of the tungsten and Cu-Cr-Zr alloy joints investigated by SEM and EDS, the joint defects were detected by ultrasonic non-destructive testing(NDT) equipment, the bond strength of joints were mearsured by mechanical tensile tester. The results show that magnetron sputtering method to deposit a 40μm-thick copper coating as the interlayer,it can significantly help to improve properties of Hot Isostatic Pressing Joining. Especially at 980 ℃, the welding module is fully prepared to meet the requirements of the ITER divertor.
