The article shows, that by producing doped carbon coatings using composite cathodes also a significant reduction of arc-induced particle emission is observed. A surface evaluation method, particularly developed for this purpose, shows a significant reduction in particle area coverage. Part 1 covers the origins of growth defects, methods of surface characterization and the experimental setup and measurement methods.enjournal article
