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Pyrogenesation Canada Inc.之间的这种新合作，它的目的是在存在氢的情况下探索微波氩等离子体在大气压力下的潜力，以减少氧化的Ti-6al-4V细和球形粉末。更确切地说，这项研究的两个主要目标是（i）开发和表征微波氩等离子体在大气压力下采用氢气压力的新配置的基本特性（ii），以在plasma属性中对基于TI的粉末进行基于TI的粉末的影响，并在PLASMA属性中融合了plassma和perii pertier的影响。预计这种基本知识的产生将在高级，等离子辅助的基于TI的粉末的开发和优化中发挥至关重要的作用，这是Pyrogenesis Canada Inc.在战略上需要应对其当前和未来的增材制造业挑战的战略性。此外，由于博士后研究员将致力于该行业重要的项目，并与该行业密切合作，因此这项研究的另一个非常重要的结果是对HQP的培训是与技能和专业知识直接相关的技能和专业知识。
