“…Although it was not demonstrated, we assume the structure of those films was 3-fold rich as the materials were simply referred to as ''diamond-like carbon''. Another report suggested that DLC films can have porosity, depending on the deposition conditions [27] which may have made them more susceptible to fragmentation. Those reports, along with the results presented here strongly suggests that amorphous carbon films with a higher 4-fold bonding character (more diamond-like) are more resistant to in vivo fragmentation, and those films with more 3-fold character (more graphitic) may be susceptible to in vivo fragmentation.…”

“…2 c as well as the calculated film porosity, it can be said that the thin films have a very low porosity suitable for biological applications. So, this could be another reason for desirable film corrosion protection as Koskinen et al [31] have also proved that for an adequate protection against corrosion.‏…”

In this study, hydrogenated amorphous carbon thin films, structurally similar to diamond-like carbon (DLC), were deposited on the surface of untreated and plasma nitrocarburised (Nitrocarburizing-treated) stainless steel medical implants using a plasma-enhanced chemical vapour deposition method. The deposited DLC thin films on the nitrocarburising-treated implants (CN+DLC) exhibited an appropriate adhesion to the substrates. The results clearly indicated that the applied DLC thin films showed excellent pitting and corrosion resistance with no considerable damage on the surface in comparison with the other samples. The CN+DLC thin films could be considered as an efficient approach for improving the biocompatibility and chemical inertness of metallic implants.

“…The intensity and width of the D-band are proportional to the resonances of carbon atoms in disordered and defective graphite structure. The stronger intensity and the wide full width at half maximum (FWHM) of the D-band denote an abundance of short range ordered graphite structures or graphite with very small grain size in the carbon film [3,19,20]. The intensity, position and FWHM of G and D bands are gained after Lorentzian deconvolution of Raman spectrum.…”
