| Abstract Scope |
For many years molybdenum and its alloys have been considered as an excellent material for the production of structural parts operating in demanding high-temperature conditions, mainly in the aviation, chemical, metallurgical, and nuclear energy industries. In recent years, a significant increase in the interest in Additive Manufacturing technologies has been observed. Plasma technologies are mentioned as the best for the manufacturing of spherical metal powders of refractory metal alloys. The paper presents the results of the production of molybdenum powder with the application of the plasma atomization method using reverse polarity RPT torches, characterized by high physical and technological properties. The influence of atomization parameters such as torches power, and plasma gas flow (argon) on such properties of the produced powders as density, specific surface area, grain size distribution, sphericity as well as chemical purity was examined. |
