The structure of diamond-like carbon thin films prepared by radio frequency chemical
vapor deposition onto the surface of different corrosion resistant alloys (304, 316L and Iconel 617)
used for coronary stent fabrication was investigated by Raman spectroscopy excited by visible (488
nm) and near-infrared (785 nm) light. The effect of electrochemical polishing of the alloy surface
and that of Ar(+) ion pre-treatment on the structure of the forming film was also studied in case of
substrate made of 316L material. It was found that in spite of simultaneous preparation the
character of the formed amorphous carbon films depends on the type of the alloy. The layer
developed on the surface of Fe-rich stainless steels (316L and 304) showed the most diamond-like
character, while the Ni-rich Inconel alloy promoted the formation of layer with high graphitic sp2
cluster content. The Ar+ pre-treatment enhanced the adhesion and the diamond-like properties of the
film while the electrochemical polishing was found to be unfavorable concerning the diamond-like
character of the layer.
