Corrosion fatigue crack propagation of AISI 316L by nitrogen ion implantation in simulated body fluid

open access: yesMetalurgija, 2021
A thin layer was formed on the surface of the AISI 316L substrate by the process of nitrogen ion implantation at a vacuum pressure of 10-6 torr, a current of 50 mA for 90 minutes with the implantation energy of 20, 40 and 60 keV.

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

open access: yesJournal 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.
