Abstract. Zinc plays an essential role in human physiological processes and has recently emerged as a promising material for biodegradable medical implants. However, its limited mechanical strength necessitates alloying with magnesium to enhance overall performance. This study investigates the physical and mechanical properties of Zn–Mg alloy composites reinforced with carbon nanotubes (CNTs) and graphene at varying concentrations (0-7 wt%). Composites were fabricated using the powder metallurgy method, and hardness, density, and porosity were evaluated using Rockwell hardness testing and the Archimedean method. Results showed that 3 wt% reinforcement provided optimal improvements. CNT reinforced composites achieved a hardness of 41.87 HRF, density of 4.62 g/cm³, and porosity of 29.25%, while graphene reinforced composites exhibited hardness of 57.30 HRF, density of 4.71 g/cm³, and porosity of 28.67%. Optical microscopy revealed uniform particle distribution at low reinforcement levels and increased pore formation at higher percentages. XRD analysis confirmed the presence of Zn, Mg, and carbon nanomaterial phases. Overall, 3 wt% CNTs or graphene significantly enhanced composite performance, indicating strong potential for biomedical applications.
