The surface topography and deuterium retention in W, Ta and W-Ta coatings under the influence of low-energy deuterium plasma was studied. It was observed formation of blisters as dome and burst or delaminated structures. The W-Ta coatings showed improved characteristics: smaller sizes and density of blisters and a significantly lower thickness of the delaminated layer.
