Abstract

Tungsten coating with a thickness of 0.6 mm on reduced-activation ferritic/martensitic steel (RAF/M) F82H (Fe-8Cr-2W) have been produced by Vacuum Plasma Spraying (VPS). Heat flux experiments using an electron beam and quantitative analyses about temperature profiles and thermal stress using FEM have been carried out on the VPS-W coated F82H. In addition, behavior of hydrogen penetration/permeation on the VPS-W coated F82H has been investigated by the tritium (T) tracer technique.
