Description
Summary:Titanium and its alloys have become the most favourite material for biomedical applications, especially orthopaedic implants. Despite its excellent mechanical properties, the chance of corrosion and ion leakage from the alloy cannot be avoided. Corrosion and ion leakage could cause systemic irritation and inflammatory effects inside the human body. Thus, coating the surface layer of the material is required. In this study, an excellent composite such as Graphene Oxide/Calcium Carbonate/Chitosan is utilized as the coating material. The surface characterization was analysed using SEM and XRD techniques. While the study of electrochemical analysis was conducted by performing EIS and Tafel extrapolations method. The result shows that the coated samples exhibit higher corrosion resistance compared to the uncoated Ti-6Al-4V. Moreover, 3 mg GO exhibit highest corrosion resistance with icorr of 1.73E-08 A.
