摘要
Commercially available polycrystalline alumina is implanted at different energies and various ion doses. Microstructural changes, elemental analysis, and evidence of compound formation of AlN and AlON are observed using scanning electron microscopy, electron dispersive X-ray spectroscopy, and GXRD techniques, respectively. Nanohardness increases due to the formation of the hard phase of nitrides. It increases with the increase in ion dose but decreases at higher ion dose. A similar trend is also observed in the corrosion resistance studied in Ringer solution. Corrosion resistance also improves with the increase in ion dose and decreases with the further increasing ion dose.
