| Abstract Scope |
Maraging steel has excellent strength at high temperatures, wear resistance, and corrosion resistance, making it an effective material for manufacturing precision molds of complex shapes. These molds are widely used in aerospace, automotive, and medical device industries for producing high-performance components requiring exceptional durability and precision. On the other hand, large amounts of valuable materials such as Ni, Co, Mo should be contained in maraging steel composition so the necessity of recycling waste products has increased.
In this study, waste maraging steel tools were recycled to produce spherical powders for additive manufacturing(AM). After producing maraging steel powders by an atomizer, post-treatment processes were performed to improve powder fluidity and the quality of AM. We investigated the particle size, sphericity, fluidity, and mechanical properties through various physical and mechanical analysis. Through this research, we aimed to derive the optimal powder manufacturing conditions for producing precision molds made by AM methods. |
