用喷射金属粉末的方法使铝合金化的冶金原理曾经有人作了论述。本文要介绍的是喷射合金化时的气体输送、粉末供给、有关的装置和喷射系统等问题,也介绍了硅粒、镁粒、锰粉和锌粉的喷射条件和操作条件以及这些合金化元素的典型实收率。此外,还从熔体质量和实际结果方面讨论了喷射技术的一些通用经验。 Metallurgical principles of aluminum alloying have been described by methods of spraying metal powders. This article addresses the issues of gas delivery, powder supply, associated equipment, and injection systems during alloying and also describes the injection and operating conditions of silicon, magnesium, manganese, and zinc powders, as well as the availability of these alloying elements The typical real yield. In addition, some common experiences with jetting technology are discussed in terms of melt quality and actual results.
