Metal ion release from nitrogen ion implanted CoCrMo orthopedic implant material [PDF]

Surface and Coatings Technology, 2006
Abstract CoCrMo alloys are used as orthopedic implant materials because of their excellent mechanical and corrosion properties. However, when placed in vivo, these alloys release Co, Cr, Mo ions to host tissues, which may give rise to significant health concerns over time. Nitrogen ion implantation can be used to form protective layers on the surface

Improving Passivation Process of Si Nanocrystals Embedded in SiO2 Using Metal Ion Implantation

Journal of Nanotechnology, 2013
We studied the photoluminescence (PL) of Si nanocrystals (Si-NCs) embedded in SiO2 obtained by ion implantation at MeV energy. The Si-NCs are formed at high depth (1-2 μm) inside the SiO2 achieving a robust and better protected system.
