    摘要:

    采用磁控濺射沉積40μm銅膜作為中間層，分別在950℃、980℃和1050℃下通過(guò)熱等靜壓（HIP）焊接技術(shù)制備了國(guó)際熱核聚變實(shí)驗(yàn)堆（ITER）計(jì)劃W/CuCrZr偏濾器部件焊接模塊，以考察溫度對(duì)磁控濺射沉積40μm銅膜作為中間層W/CuCrZr偏濾器部件焊接質(zhì)量的影響。通過(guò)掃描電子顯微鏡（SEM）和X射線能譜（EDS）分析焊接界面的形貌和成分，利用超聲波無(wú)損探傷（NDT）儀對(duì)焊接界面缺陷進(jìn)行了檢測(cè)，利用力學(xué)拉伸試驗(yàn)機(jī)考察了焊接界面的結(jié)合強(qiáng)度和CuCrZr合金的力學(xué)性能。結(jié)果表明：磁控濺射法沉積40μm銅膜作為中間層，可以有效的提高HIP焊接界面質(zhì)量。特別是在980℃時(shí)，所制備的焊接模塊能夠滿足ITER計(jì)劃對(duì)于偏濾器部件連接性能的要求。

    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.
