Abstract :In this study, the production of AM60 magnesium alloy powder by gas atomization method was experimentally investigated. Experiments were carried out at a constant temperature of 770 °C, 35 bar atomizing gas pressure and 4 different nozzle diameters insert ignore into journalissuearticles values(2, 3, 4, 5 mm);. Argon gas was used to atomize the melt. Scanning electron microscopy insert ignore into journalissuearticles values(SEM); was used to determine the shape of the AM60 powders produced, XRD and XRF analyzes were used to determine the internal phases of the produced powders and percentage of these phases, and laser measurement devices were used for powder size analysis. The overall appearance of the AM60 magnesium alloy powders produced is complex, ligament, rod, droplet, flake and spherical but the shape of the powder is mostly dripping and spherical depending on the reduction of the nozzle diameter. The finest powder obtained was found to have a gas pressure of 35 bar at a temperature of 770 °C, a diameter of 2 mm, and the overall shape of the powder was found to be complex.
