Powder Metallurgy

用于添加剂制造工艺的金属粉末的初始质量和进一步处理在最终产品的质量和特性中起着重要作用。建立了诸如粒度，分布和粒子形态之类的参数，但这些参数仅代表表征的“机械”部分，忽略了冶金和化学效应，尽管粒子化学影响最终印刷或成型零件的基本性能。

To ensure that the final parts made with these techniques meet the rigorous requirements of medical, automotive, and aerospace applications, metal powders used as inputs must be fully characterized and monitored though out the production cycle: during the powder atomization/production process, upon incoming QA/QC at the part production facility, during storage and part production, and after powder recycling. Especially the powder recycling process on expensive high-end alloy like Ti64, AlSi₁₀Mg is delicate but determines the number of recycling steps and therefore the yield of the entire process.
