The surface topography of W bulk prepared by powder sintering (20 μm thickness) and W coatings deposited by cathodic arc evaporation and by argon ion sputtering was studied under the influence of low-energy hydrogen (deuterium) and helium plasma at room temperature. The surface modifications induced by the plasma irradiation were studied by scanning electron microscopy. It was observed formation of blisters and sputtering. After helium and deuterium plasma irradiation, numerous blisters were observed on the surface of W foils samples and coatings deposited by argon ion sputtering. The surface of W coatings deposited by cathodic arc evaporation was undergone only sputtering process under the same irradiation conditions.
