Bonding and bio-properties of hybrid laser/magnetron Cr-enriched DLC layers

Popis výsledku v původním jazyce

Chromium-enriched diamond-like carbon (DLC) layers were prepared by a hybrid technology using a combination of pulsed laser deposition (PLD) and magnetron sputtering. XRD revealed no chromium peaks, indicating that the layers are mostly amorphous. Carbon (sp2 and sp3 bonds) and chromium bonds were determined by XPS from C 1s, O 1s, and Cr 2p photoelectron peaks. Depending on the deposition conditions, the concentration of Cr in DLC layers moved from zero to 10 at.% for as-received sample surfaces, and to about 31 at.% after mild sputter-cleaning by argon ion cluster beam. It should be noted that the most stable Cr3+ bonding state is in Cr2O3 and Cr(OH)3, and that there is the toxic Cr6+ state in CrO3. The surface content of hexavalent chromium in the Cr 2p3/2 spectra is rather low, but discernible.n
