Biocompatibility, Antibacterial Activity and Preparation of Ce doped ?-TCP by RF Sputtering Technique to Enhancing Some Properties
Keywords:Ce doping; ?-TCP; Biocompatibility; Antibacteria
Two weight percents of ceria (40 and 80 wt%) were added to tricalcium phosphate to improve some
properties for Ce doped ?-TCP by RF sputtering method on stainless steel substrate as coating for biomedical
applications. The sputtering was done at 150 W and 150oC. The confirming of doping was achieved by some
techniques such as XRD, FESEM/EDS and EDS mapping, and indicated the occurring of incorporation
between cerium oxide and TCP as thin film. Biocompatibility and antibacterial test was improved after
adding cerium oxide to TCP which candidate the prepared thin film for bio implants. Microhardness also
examined for prepared composites to show the increasing microhardness of CeO2/TCP coatings compared
with conventional HA coating
