Thin TiN and Diamond Like Coatings (DLC) were created by a technologic
al process and by Dual Beam IBAD technique on pure iron enriched at th
e surface in Fe-57. The local microscopic electron states at the inter
faces were studied by Conversion Electron Mossbauer Spectroscopy while
the long range migrations bf element were concluded from Rutherford B
ack Scattering Spectroscopy.
