Kyhe Technology's self-developed patented technology for "High-Flowability Low-Oxygen Recycled Titanium Alloy Powder and Its Preparation Method" successfully transforms recycled titanium scrap into high-performance 3D printing powder through an innovative multi-stage purification-plasma spheroidization-in situ passivation process. The technology employs hydrogenation-dehydrogenation combined with electromagnetic separation for deep purification, utilizes plasma spheroidization to achieve powder sphericity ≥95%, and innovatively forms a nano-scale protective layer in inert atmosphere. The resulting powder exhibits outstanding characteristics with oxygen content ≤1000ppm and Hall flow rate ≤25s/50g, enabling printed parts with density ≥99.5%. Compared to conventional processes, it reduces energy consumption by 40% and increases scrap utilization rate to over 90%. Currently, this technology has been successfully applied in aerospace lightweight components and medical implant manufacturing.
