The New Technology Has Doubled the Strength of 3D Printing Aluminum Composites
Pages: 23

Journal: Office Automation

Abstract: NUST MISIS科学家研发出一种生产超高纯度氧化铝(UHPA)的先进工艺,这种工艺可使3D打印铝制复合材料的强度翻倍,成品质量堪比钛合金.此外,他们开发的3D打印设备改良剂可以应用于航空航天工业产品.这种改良剂是通过氮化物和氧化铝的燃烧获得,是新型复合材料的基础物质.NUST MISiS使用纯度为99.7%的铝颗粒,通过氧化、碱反应、盐酸处理和1450℃的热煅烧,去除UHPA中的杂质,特别是铁杂质,而碱金属(K,Na,Li)的浓度反而增加了.
