Deuterium (D) plasma-driven permeation (PDP) experiments for a Chinese reduced activation martensitic/ferritic steel CLF-1 have been performed. The effects of implantation flux, sample temperature and ion incident energy have been studied. The steady state PDP flux is found to be proportional to the square root of the implantation flux, indicating that the permeation takes place in recombination-limited regime for the upstream surface and diffusion-limited regime for the downstream surface (RD). The PDP flux and flux ratio (PDP flux/implantation flux) decrease with the increase of ion incident energy, which may be due to the enhancement of D recombination coefficient at the upstream surface.
