A functionally graded material-based actively water-cooled tungsten-copper mockup with a dimension of 30 mm×30 mm×25 mm was designed and fabricated by infiltration-brazing method.The thicknesses of the pure W layer and W/Cu graded layer were 2 and 3 mm,respectively.High heat flux tests were performed on the mockup using an e-beam device.There is no damage occurring on the joint after heat loading at 5 MW/m2.The temperature on the pure W surface is less than 500°C after irradiation for 100 s at 5 MW/m2,while the temperature on the brazing seam/copper surface is around 200°C.
A functionally graded material-based active water-cooled tungsten-copper mockup with a dimension of 30 mm × 30 mm × 25 mm was designed and manufactured by infiltration-brazing method. The thicknesses of the pure W layer and W / Cu graded layer were 2 and 3 mm, respectively. High heat flux tests were performed on the mockup using an e-beam device. There is no damage occurring on the joint after heat load at 5 MW / m2. The temperature on the pure W surface is less than than 500 ° C after irradiation for 100 s at 5 MW / m2, while the temperature on the brazing seam / copper surface is around 200 ° C.
