An ideal hip implant should consist of materials with a high resistance to wear and good biocompatibility. Despite extensive research conducted in this area, there is no available implant capable of resisting bone resorption while providing implant stability. This study aims to develop a new method for grafting the surface of selective laser melted (SLM) titanium alloy (Ti-6Al-4V) with poly (2-methacryloyloxyethyl phosphorylcholine) (PMPC) to overcome this problem. In the first part of this study, PMPC was grafted onto the SLM fabricated Ti-6Al-4V. The surface of the grafted polymer was subsequently characterised by Scanning electron microscopy (SEM), 3D optical profiler, energy-dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and Fourier transform infrared spectroscopy (FTIR). As indicated in the results, the main advantage of using this polymer is the presence of phosphorylcholine, mostly on surfaces, which reveals the existence of a strong chemical bond between the grafted layer (PMPC) and substrate (Ti-6Al-4V).
