It was found that, in addition to the cubic phase of TiCxOy oxycarbide, the films contain carbon in the amorphous, presumably graphite-like state. In carbon C1s spectra, bands at 282.0, 284.4, and 286.0 eV correspond to the TiCx state, amorphous carbon, and C–C bonds, respectively. The maximum at 283.0 eV was interpreted as the C state in titanium carbide nanoforms, i.e., Ti14C13 clusters or Ti8C14 carbohedra. The phase ratio was varied by coating deposition conditions, i.e., TiC/a-C deposition by Ti cathode sputtering in C2H2/Ar, and composite Ti/C target sputtering in Ar and C2H2/Ar. When using the Ti cathode and C2H2/Ar gas mixture, the ratio of carbide and amorphous a-C phases was estimated as 1 : 1; the surface layer ~15 nm thick was enriched with amorphous carbon. It was assumed that TiC/ a-C composite coatings with an additional a -C film on the surface would have an increased stability in reaction media and good biocompatibility Доп.точки доступа: Kuznetsov, M.
