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.
