Abstract. Powder Metallurgy (PM) is an advanced manufacturing technique that enables the fabrication of materials with unique microstructures and properties. Magnesium (Mg) alloys, particularly magnesium–zinc (Mg-Zn) alloys, are gaining popularity in biomedical applications due to their lightweight nature, good strength, and compatibility with biological systems. However, their mechanical and corrosion properties still need improvement, which can be achieved through alloying and reinforcement. This study investigates the effect of different sintering temperatures on the hardness and corrosion behavior of Mg-3wt.% Zn/6wt.% β-Tricalcium Phosphate (β-TCP) composites. Mg-3wt.% Zn was mixed with 6wt.% β-TCP powder using a roll mill at 120 rpm for 60 minutes. The mixture was then compacted at a pressure of 200 MPa. Sintering was conducted in an argon-controlled atmosphere at temperatures of 450°C, 500°C, and 550°C. The microstructure of the sintered samples was examined using an optical microscope, and Vickers microhardness testing was used to measure hardness. The corrosion behavior was evaluated using a potentiostat. Results showed that sintering at 450°C produced the highest hardness and good corrosion resistance.
