Sputtering yield and morphological changes of TiB2 coatings induced by different incident beams
MetadataShow full item record
The properties of TiB2 coatings deposited by direct electron-beam evaporation and by plasma spray deposition as well as their behavior during the interaction with the energetic beam are discussed. These coatings are considered as a plasma facing material for some parts of the next step tokamak. Sputtering yields were determined for: Ar+ ion bombardment in the energy region 3-12 keV and laser beam bombardment in the range up to 10(9) W/m(2). It was found that whatever the mechanism of sputtering is, a similarity between sputtering yield and energy dependence for used combinations of incident beams and target does exist.
