Biocompatibility of DLC coatings |
| Remarks： |
Diamond-like carbon (DLC) coatings were prepared, by filtered cathodic vacuum arc technique, on Co–Cr–Mo alloy to investigate the tribological behaviour of uncoated and DLC coated Co–Cr–Mo sliding against similar counter-faces. The tribological evaluation in simulated body fluid reveals that the friction and wear rate of DLC coated Co–Cr–Mo sliding pair is significantly lower compared to that of the uncoated Co–Cr–Mo sliding pair. A comparison on the performance of the above discloses the possibility of DLC coated Co–Cr–Mo alloy for orthopaedic applications. The evaluation of surface hardness using nano-indenter reveals that the DLC coated Co–Cr–Mo alloy is much harder (~3 times) than that of the uncoated. In addition a preliminary study has also been carried out, on the uncoated and DLC coated Co–Cr–Mo alloy samples, to examine the biocompatibility (cytotoxicity evaluation to look at the cell morphology and cell viability) of the DLC coated sample with respect to that of the uncoated sample. The study reveals that the DLC coating is little more biocompatible, but cell adhesion is slightly lower than that of uncoated Co–Cr–Mo sample.
