该项目将介绍用于添加剂制造的等离子转移弧工艺(PTA-AM)的使用。 在石油和天然气行业的应用。由于油砂的高磨损和腐蚀作用，金属基质 油砂作业需要使用复合材料(MMC)。通常，NiCrSiB合金粉末是混合的 与碳化钨(WC)粉末一起，通过喷嘴送入由惰性气体保护的等离子体中，并 沉积在衬底上的。对于PTA-AM应用程序，我们建议逐层构建两个感兴趣的部分 对于Syncrate和特定于他们的操作，有一个法兰管道和一个喷嘴喷头。这将是第一次 加拿大对AM使用PTA工艺的研究，可能是世界上第一个应用MMC的研究。 该项目将涉及来自阿尔伯塔大学和InnoTech的四名研究人员之间的合作 艾伯塔省。通过结合两个小组的专业知识，可以充分证明这种方法应用于AM的可行性 探索过了。随着我们预期成功，我们与InnoTech Alberta的合作将确保出色的 技术应用于工业和未来的放大研究。对于这个项目，材料的综合专业知识 处理，Henein，PTA的运作，Wolfe，为AM应用重新设计PTA，Qureshi，以及 对AM样品的冶金分析，Li，提供了跨学科专业知识的独特组合。 这种专业知识的结合也将为高素质人才的培养提供独特的氛围 人员(总部)。我们计划在计划的四年中，每年有三名学生参与这个项目。 持续时间。还需要50%的研究助理时间才能提供日常监督 学生使用差示扫描量热仪等实验室设施。为了方便将来 扩大规模实验测试将在位于艾伯塔省InnoTech的PTA装置进行。接入成本 包括在提案中，以及创新科技艾伯塔省支持这一点的实物捐助 协作。如详细介绍的那样，辛克鲁德同时提供现金和实物捐助。

This project will address the use of the Plasma Transfer Arc process for Additive Manufacturing (PTA-AM) applications in the oil and gas industry. Due to the high wear and corrosion action of oil sands, metal matrix composites (MMCs) are required for use in oil sands operations. Typically a NiCrSiB alloy powder is mixed with tungsten carbide (WC) powders and fed through a nozzle into a plasma protected by inert gas and deposited onto a substrate. For PTA-AM applications, we propose to build layer by layer two parts of interest to Syncrude and specific to their operations, a flanged pipe and an injection nozzle head. This will be the first research study of AM using the PTA process in Canada and likely the first in the world for MMC applications. This project will involve a collaboration between four researchers from the University of Alberta and InnoTech Alberta. By combining the expertise of both groups, the feasibility of this approach to AM can be fully explored. As we anticipate success, our collaboration with InnoTech Alberta will ensure excellent transfer of technology to industry and for future scale-up studies. For this project, the combined expertise of materials processing, Henein, the operation of the PTA, Wolfe, the re-design of PTA for AM applications, Qureshi, and the metallurgical analysis of the AM samples, Li, offers a unique combination of interdisciplinary expertise. Such a combination of expertise will also provide a unique atmosphere for the training of Highly Qualified People (HQP). We plan to have three students working on this project each year of its proposed four year duration. A 50% time of a Research Associate is also required in order to provide day to day supervision of students using laboratory facilities such as Differential Scanning Calorimetry. In order to facilitate future scale-up the experimental tests will be carried out at the PTA unit located at InnoTech Alberta. Costs of access are included in the proposal as well as in-kind contributions from InnoTech Alberta in support of this collaboration. Syncrude is providing both cash and in-kind contributions as outlined in detail.
