Tóm tắt

This study investigates the integration of graphene oxide (GO) into low nickel bio-grade stainless steel (LNBGSS) to enhance its corrosion resistance and assess its biocompatibility. Three concentrations of GO (0.5, 1.0, and 1.5 wt%) were added to the steel matrix using the powder metallurgy method and annealed in a nitrogen environment. X-ray diffraction and field-emission scanning electron microscopy analyses reveal that while the crystal structure of the steel remains largely unchanged, the morphology of the prepared samples exhibits minimal alteration post-GO integration. The average particle sizes (D
