Study the Structure and Properties of TiO₂/HAp Coating onto Ti-6Al-4V Alloy Using Electrophoretic Deposition

Abstract:

In the present study, (TiO2/HAP) and TiO2 coatings were fabricated with electrophoreticdeposition on substrate for titanium alloy. This study aims to increase improve this alloyantibacterial properties by coating the surface with a bio ceramic (TiO2 and TiO2/HAP)nano-powders. Coating on Ti-6Al-4V with an electrophoretic deposition(EPD) technique,ideal conditions of 20V and a deposition time of (4 min). The surface properties of coatedsubstrates, such as, micro-hardness, surface roughness and wettability antibacterial test wereevaluated and compared to that of the uncoated substrate. The results showed that theelectrophoretic deposition is a favorable technique to make a bio coating on Ti-6Al-4Vsubstrate with excellent properties and structure for applications biomedical.The average micro-hardness of the TiO2/HAP coated sample is 1024 HV compared withthat of uncoated substrates is 80 HV. The average thickness of TiO2/HAP coating isdetermined to be (18µm) on the substrate surface at factor deposition time (4 min). The resultsof previous research indicate that the high wettability and surface roughness at the micronscale were for the synergistic effect of reduction on cell adhesion and growth.
