Description
Summary:Titanium and its alloys are implantable metals as artificial bone replacements due to their exceptional mechanical qualities and biocompatibility but poor titanium osseointegration should be fixed by coating the surface with good osseointegration materials. Our current research focused on enhancing the biocompatibility as well as corrosion resistance of commercially pure titanium substrate by constructing bio composite coating, various percentages (2,6, and 10) wt.% of Niobium Oxide (Nb2O5) powder were combined with (98,94, and 90) wt.% of polymethyl methacrylate (PMMA) powder coating by electrostatic spray deposition technique(ESD). The effects of Nb2O5 percentages in the PMMA matrix on the surface properties of titanium were deeply analyzed. The surface morphology of the coated layers was determined using FESEM/EDS mapping and XRD techniques. A homogeneous, uniform, and crack-free coating layer were achieved. The contact angle test and anti-bacterial test were used to investigate the biological behavior of the coated samples, which revealed that they had good wetting characteristics and good inhibition of bacterial growth.
