Electron Emission from Inconel under Ion Bombardment

Electron yields from clean and oxydized Inconel 625 surfaces have been measured for H', H:, Hef, 0' and Ar+ ions at normal incidence in the energy range 1.5-40 keV. These measurements have been made under ultrahigh vacuum and the samples were freed of surface contaminants by bombarding with high doses of either 20 keV H l or 30 keV Ar+ ions. Differences in yields of oxydized versus clean surfac...

Model of Evolution of Surface Grain Structure under Ion Bombardment

Diffusion and chemical reactions in multicomponent systems play an important role in numerous technology applications. For example, surface treatment of materials and coatings by particle beam leads to chemical composition and grain structure change. To investigate the thermal-diffusion and chemical processes affecting the evolution of surface structure, the mathematical modeling is efficient a...
