| Abstract Scope |
Additive Manufacturing (AM) that enable the production of elements with personalized shapes allow for the reduction of the amounts of used material and waste generated during the process. The possibility to reduce the consumption of raw materials during the production of components is particularly important in the case of refractory metals. One of the limitations to the wider use of AM technology for the production of components from refractory metals is the availability of powders.
As a result of the performed works, a method that allows the production of spheroidal powders from molybdenum or tungsten doped with rhenium was developed. This method is based on powder metallurgy processes such as thermal reduction and plasma spheroidization. The manufactured powders were used to produce combustion chamber demonstrators for satellite engines using the LBPF method. The influence of LBPF process parameters on the properties of the manufactured materials was examined. |
