Through this new collaboration between UdeM and PyroGenesis Canada Inc., it is aimed to explore the potential of microwave argon plasmas at atmospheric pressure in presence of hydrogen for reduction of oxidized Ti-6Al-4V fine and spherical powders. More precisely, the two main objectives of this research are (i) to develop and characterize the fundamental properties of a new configuration of microwave argon plasmas at atmospheric pressure in presence of hydrogen specially intended for the processing of powders, (ii) to incorporate Ti-based powders in the microwave plasma and investigate their impact on the plasma properties and, conversely, of the plasma on the properties of Ti-based powders. The generation of such fundamental and applied knowledge is expected to play a crucial role in the development and optimization of advanced, plasma-assisted reduction processes of Ti-based powders that is strategically needed by PyroGenesis Canada Inc. to meet its current and future challenges in additive manufacturing. Additionally, since a postdoctoral fellow will work on a project of prime importance to the industry and in close collaboration with the industry, another very important outcome of this research is the training of HQP with skills and expertise directly relevant for several high-technology sectors.

通过UdeM和PyroGenesis Canada Inc.之间的新合作，目的是探索微波氩等离子体在氢气存在下还原Ti-6Al-4V氧化细颗粒和球形粉末的潜力。更确切地说，本研究的两个主要目标是：（i）在大气压力下，在氢气存在下，专门用于粉末处理的微波氩等离子体的新配置的基本特性的开发和表征，（ii）将钛基粉末纳入微波等离子体中，并研究其对等离子体特性的影响，反之，等离子体对钛基粉末性能的影响。此类基础知识和应用知识的产生预计将在PyroGenesis Canada Inc.战略需要的先进等离子体辅助钛基粉末还原工艺的开发和优化中发挥关键作用。以应对其在增材制造领域当前和未来的挑战。此外，由于博士后研究员将从事对行业至关重要的项目，并与行业密切合作，因此本研究的另一个非常重要的成果是HQP的培训与几个高科技部门直接相关的技能和专业知识。
