德国布来梅市的Ｆｒａｕｎｈｏｆｅｒ研究所开发了一种利用往金属流中注射惰性颗粒(如氧化物和碳化物)的喷射成形技术制取金属基复合材料(ＭＭＣ)的方法。他们设计制成了一种专用装置,能够将大量的强化剂颗粒均匀地分散到金属基体中,是利用氮气流通过一种特殊设计的环形喷... The Fraunhofer Institute in Bremerhaven, Germany, has developed a method of preparing metal matrix composites (MMCs) using a spray forming technique that injects inert particles (such as oxides and carbides) into the metal stream. They designed a special device, which can disperse a large amount of reinforcing agent particles evenly into the metal matrix, using nitrogen flow through a specially designed annular jet ...
