Experimental Investigation of the Effect of Reduced Graphene Oxide Addition on the Mechanical Properties and Behavior of Ti/RGO Composites in Spark Plasma Sintering Process with Reference to Potential Applications in Medical Implants

Given the strategic importance of pure titanium in sensitive industries, such as healthcare, and the existing weaknesses in the mechanical and physical properties of this metal, the present study aims to investigate the enhancement of its mechanical properties through the composite fabrication of pure titanium with Reduced Graphene Oxide (RGO) nanoparticles based on Spark Plasma Sintering (SPS) method. During the fabrication process, the mechanical properties of the samples were evaluated and compared using specialized tests. Composite fabrication is one of the effective and common methods for improving the material properties. As demonstrated in the results obtained in this study, the SPS method can be proposed as a reliable method for producing high-quality composites. Further evaluation of the mechanical properties of the samples reinforced with RGO indicates that the optimal presence of this reinforcement significantly enhances the mechanical properties compared to those of the pure samples. Moreover, the analysis of the behavior of the produced samples during the sintering process indicates a significant increase in the force and pressure in samples containing reduced graphene oxide, with no observed significant changes in displacement and temperature.
