Comparison of damages in tungsten and tungsten doped with lanthanum-oxide exposed to dense deuterium plasma shots
Abstract
Changes in the surface and structure of tungsten and tungsten doped with 1% lanthanum-oxide samples irradiated by powerful deuterium plasma shots are investigated. Comparative analysis of the samples microroughness, the damage factor estimated from SEM images, and the hardness of cross-sections has been carried out. It can be concluded that the doping of tungsten with 1% lanthanum-oxide may decrease the development of a mesh of microcracks on the irradiated surface. However, this doping may increase the microroughness of the sample surface.
