Linking powder quality to part quality for Mg-containing monodisperse Al powders

几种添加剂制造(AM)技术正在为制造商提供，以实现先进和更高性能的工业部件。影响AM部件完整性的主要因素之一是起始材料的质量，更具体地说，是粉末床熔化过程中的粉末材料的质量。了解和表征粉末被认为是一项关键和必要的工作。Equisphes(EQS)位于大渥太华地区，是制造用于AM和金属喷涂涂料的超高性能球形金属粉末的世界领先企业。EQS生产自由流动、均匀、单一颗粒、无团聚的球形金属粉末，带来了目前市场上无法获得的卓越控制和性能效率。这种粉末的粒度分布窄，具有良好的球形性和流动性，无需筛分，旨在显著提高终端产品和应用的质量。本CRD建议的目的是进一步了解一系列铝粉成分的独特特征，范围从成熟的配方(以建立基准)到以前从未经过检验的更具发展性的合金，以更好地执行铝合金成分工程。该提案还寻求测量由其优化的粉末制成的零件的静态和动态性能，并努力在粉末特性和后处理方面获得新的见解，以提高零件的性能。

Several additive manufacturing (AM) technologies are becoming available to manufacturers to realize advanced and more performing industrial parts. One of the main factors influencing the integrity of AM parts is the quality of the starting material, and more specifically powdered materials in powder bed fusion processes. Understanding and characterization of the powders is recognized as a critical and necessary effort. Equispheres (EQS), located in the greater Ottawa area, is a world leader in fabrication of ultra-high-performance spherical metal powders engineered for AM and Metal Spray Coatings. EQS produces free-flowing, uniform, monograin, agglomerate-free spherical metal powders, which bring superior control and performance efficiencies that are currently unavailable in the marketplace. The powders have a narrow particle size distribution, excellent sphericity and flowability, without sieving, and are designed to significantly improve the quality of end-use products and applications. The purpose of this CRD proposal is to further understand the unique characteristics for an array of Al powder compositions ranging from well-established formulations (to establish a baseline) to more developmental alloys that have not been examined before to better perform Al alloy composition engineering. The proposal also seeks at measuring the static and dynamics properties of parts made from their optimized powders and to strive for new insights in powder characteristics and post-processing to increase parts performance.
