Method for preparing low-oxygen-content vacuum gas atomization 3D printing high-temperature alloy powder

The invention belongs to the technical field of 3D printing, and discloses a method for preparing low-oxygen-content vacuum gas atomization 3D printing high-temperature alloy powder. The method aims at solving the problem that in the prior art, the oxygen content in high-temperature alloy powder preparation is high. The method comprises the steps of preparing and treating an alloy master alloy rod, conducting center drilling, preparing alloy powder and the like. According to the method, the specific surface area of raw materials is reduced in the manner that drilling cutting replaces small material cutting, under the condition that alloy powder preparation is not influenced, the oxidation phenomenon appearing in the preparation process is reduced, the oxygen content of the powder is greatly reduced, and the oxygen content of the powder reaches the industry standard and is far superior to the industry standard. According to the method, a water jet cutter operation process is omitted, consumables can be saved,
