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

Metalurgija, 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.

Low energy ion-solid interactions: a quantitative experimental verification of binary collision approximation simulations

Materials Research Express, 2023
Ultra-low energy ion implantation has become an attractive method for doping of two-dimensional materials and ultra-thin films. The new dynamic Monte Carlo program IMINTDYN based on the binary collision approximation allows a reliable prediction of low ...

Incorporation of Selenium into Sol–Gel‐Derived Bioactive Glass: Influence on Glass Structure, Bioactivity, and its Selective Cytotoxicity

Advanced Engineering Materials, EarlyView.
Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.

Modeling of the transient interstitial diffusion of implanted atoms during low-temperature annealing of silicon substrates

, 2011
It has been shown that many of the phenomena related to the formation of "tails" in the low-concentration region of ion-implanted impurity distribution are due to the anomalous diffusion of nonequilibrium impurity interstitials.

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...
