Abstract: Recently, magnesium alloys including AZ31 have attracted attention in bone regeneration applications such as temporary orthopedic implants due to their high biocompatibility and biodegradability. In the present work, graphene oxide was synthesized by the Hummer process and deposited on magnesium alloy AZ31 by spin coating. The effect of graphene oxide on the surface morphology was defined by Scanning Electron Microscopy and Fourier Transformation Infrared Spectroscopy. Also, the adhesion of graphene oxide to magnesium alloy substrates was evaluated using a scratch tester. Furthermore, the friction and wear behavior of the coatings were tested using multiple scratches. The results show that the graphene oxide coating was successfully deposited on magnesium alloy, and its good adhesion and high wear resistance provide potential for future orthopedic applications.
