Ion beam mixing and radiation enhanced diffusion in metal/ceramic interfaces

Thermal stability of nanostructurally stabilized zirconium oxide

“…No argon signals were even observed in the RBS spectra of as-deposited ZrO 2 films on grafoil (carbon) substrates. This is in contrast to the previously reported RBS measurements of ZrO 2 films made by IBAD [26] or the ion beam mixing process [25] with 10-150 keV Ar beam where the presence of argon can be easily found in their depth profile data.…”

“…Optimization of the ion bombardment conditions can also modulate the morphology, density, stress level, crystallinity, and chemical composition of the as-produced fi lms with excellent adhesion to the substrates. IBAD has been previously applied and studied for ZrO 2 fi lm deposition [25,26] using argon ions in the kiloelectronvolt energy range which resulted apparently in non-stoichiometric opaque zirconia. We have also observed similar results in our laboratory when only Ar ions, especially with high energy ions and high current density, were used to fabricate ZrO 2 fi lms.…”

“…We have also observed similar results in our laboratory when only Ar ions, especially with high energy ions and high current density, were used to fabricate ZrO 2 fi lms. Furthermore, bombardment of material with kiloelectronvolt energy range ions often resulted in accumulation of projectiles such as argon [25,26] and even formation of nitrogen bubbles [27] or solid krypton [28].…”
