Wear of Ion Implanted Glassy Carbon
Published online by Cambridge University Press: 25 February 2011
Abstract
Significantly improved wear properties are described for glassy carbon following implantation with 2 MeV helium and 50 keV nitrogen to doses in the range 1015–1017 ions cm−2. Implanted material is up to 100 times more wear resistant to diamond abrasion than unimplanted material. Enhanced wear resistance is available at the surface with nitrogen but lies below the surface with helium, reflecting the difference in modified depth associated with implant energy and ion mass. Unusually for ion implantation, dose related surface compaction is observed for both nitrogen and helium. Changes in microstructure during implantation with particular regard to collision processes and amorphisation of the graphitic fraction of glassy carbon are discussed.
