美国空军研究实验室材料制造董事会和美国国防先进研究项目机构(DARPA)开发了一项能使飞机燃气轮机引擎生产过程流水化的喷射成形工艺。目前,该技术正转向航空航天业的应用。 作为DARPA的一项133万美元的研究项目,为了提供一种有效的可供选择的替换生产工艺,喷射成形对超合金锭坯、近终形能力和快速金属沉积速率实行了直接的一步转变法。喷射成形技术减少了许多过去制造航空航天用燃气轮机环件和壳体工艺需要的步骤,并且使元件的材料成本降低了30％。此工艺还使生产快速感应样机和小批量产品成为可能,并且还能减少元件输送的引导时间。 Pratl ＆ Whitney和Howmet是两个致力
The Air Force Research Laboratory Materials Manufacturing Board and the Defense Advanced Research Projects Agency (DARPA) have developed a jet-forming process that will streamline the production of an aircraft gas turbine engine. At present, the technology is turning to the aerospace industry. As a $ 1.33 million research project by DARPA, jet-forming is a direct one-step conversion of superalloy billet, near-net-shape capabilities and rapid metal deposition rates in order to provide an effective alternative manufacturing process . Spray forming techniques reduce many of the previous steps required to manufacture aerospace ring and shell processes for aerospace applications, and reduce the material cost of components by 30%. This process also makes it possible to produce quick-response prototypes and small batch products, as well as reducing the lead time of component delivery.
