摘要
Vacuum plasma spray （VPS） is one of the candidate fabrication techniques of the first wall and divertor modules of ITER. VPS-W coated carbon materials are widely applied at the present stage in order to be compatible with the support structure of current fusion devices, in which rhenium as intermediate layer is a well-established technique, for example, VPS-W coated fine grain graphite and carbon fiber composite made by Plansee Aktiengesllshaft. As for VPS-W/Cu coating, thick coating of about 5 mm has been developed by ENEA （Russian） and JAERI （Japan） for diverter modules of ITER, which can sustain 1000 cycles at a heat flux of 5 MW/m^2 without damage. In the present work.
