Ti6Al4V coating for carbon/carbon composites synthesized by magnetron sputtering: microstructure and in-vitro biotests

In order to improve the cell compatibility of biomedical carbon/carbon composites, Ti6Al4V coatings were applied on carbon/carbon composites by magnetron sputtering technique. The microstructure and cell responses of the coatings were evaluated, and the bonding strength between the coatings and carb...

Description
Summary:In order to improve the cell compatibility of biomedical carbon/carbon composites, Ti6Al4V coatings were applied on carbon/carbon composites by magnetron sputtering technique. The microstructure and cell responses of the coatings were evaluated, and the bonding strength between the coatings and carbon/carbon composites was analyzed. The Ti6Al4V coatings modulated the surface morphology, decreased the surface roughness, improved the surface wettability and achieved a strong bonding strength to carbon/carbon composites. The cells showed larger cell extension and higher cell proliferation for the Ti6Al4V coatings than for the carbon/carbon composites. Copyright © 2012 John Wiley & Sons, Ltd.
