Tribological and physical properties of pure magnesium (Mg) are investigated during sintering for 2, 4, and 6 h at the temperature of 600°C. The pure sintered magnesium is characterized by wear behavior, corrosion, scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), unit weight, water absorption, specific weight, and micro-Vickers hardness testing. XRD analysis of sintered Mg revealed the existence of Mg, MgO, and MgO2 compounds. The hardness of the pure magnesium ranged from 53.8 to 70.4 HV0.1. The wear tests are carried out in a ball-disc arrangement under a dry friction condition at room temperature with an applied load of 5 N and a sliding speed of 0.2 m/sec at a sliding distance of 250 m. The wear surfaces of the Mg samples are analyzed using SEM and EDS. It is observed that the wear rate of pure Mg decreased by 54% when the sintering duration is increased. The corrosion resistance of Mg sintered for 6 h is increased by 36% compared to Mg sintered for 2 h.
