RHEED characterisation of the near surface microstructure of Ti-O based biocompatible coatings [PDF]

open access: yes, 2004
Mechanically polished, annealed, nitric acid treated and aged in boiling water after nitriding, commercially pure Ti substrates have been characterised using reflection high-energy electron diffraction (RHEED) and secondary electron imaging, in terms of ...
