A method for preparing high-performance tungsten-based metal parts belongs to the technical field of powder additive manufacturing. First, spray pyrolysis and hydrogen reduction pre-sintering are used to prepare tungsten rhenium alloy powder with high purity and uniform chemical composition. Then two jet milling techniques are used to improve the state of raw tungsten powder and tungsten rhenium alloy powder, and then reduced in a hydrogen atmosphere to finally obtain high-quality nearly spherical tungsten rhenium alloy powder. At the same time, the complicated shape of the workpiece schematic diagram and the optimal processing strategy are designed through the computer modeling software, and the printing file is exported to realize the modeling. Finally, after mixing the tungsten powder and the tungsten rhenium alloy powder in a proportion, the final complex shape of the tungsten rhenium-based alloy parts is prepared in the SLM selective area laser melting equipment. The invention combines the spray pyrolysis process and the jet mill process to significantly optimize the raw material powder, and the tungsten-rhenium alloy parts prepared by selective laser melting are close to full density, uniform structure and excellent comprehensive mechanical properties.
