Bulk Electroforming and Cold-Spraying of Advanced High-strength/Corrosion-resistant/Anti-wetting Alloys and Composites

这项为期5年的研究计划涉及几组先进的电铸和冷喷涂材料的开发、表征和性能测量，这些材料目前在世界其他地方是无法获得的。第一类是耐腐蚀铜，通过在旧燃料容器(UFC)的外表面电铸/冷喷涂来制造，用于安全和长期(100万年)储存加拿大核反应堆船队在深层地质储存库(DGR)产生的放射性废物。DGR的建设预计将于2033年开始，并于2040年初投入运营。我们研究计划的这一部分是多研究人员、多大学研究努力的重要组成部分，目的是研究UFC在预期的DGR环境下的长期表现。第二类材料涉及高强度和高温稳定的电铸纳米晶合金(Ni-Co、Co-P和高熵合金)的开发，这些合金可以在航空航天或汽车工业中得到应用。最后一组电铸材料用于超疏水复合电铸，作为先进的换热和耐腐蚀材料应用于加拿大电力工业的热交换器。合金和复合材料电铸工作有望在5-10年的中期时间框架内生产出新材料。这项研究建立在申请人和他的研究团队之前在先进纳米晶体电沉积和晶界工程材料领域的成功材料开发的基础上。该计划将与核废物管理组织(NWMO，多伦多)、国家研究委员会(NRC，Boucherville)和Integran Technologies，Inc.(密西索加)密切合作执行。这项研究将有助于培训19名高素质人员(HQP)，他们将直接与合作外部合作伙伴的几名研究人员互动。这一基础研究计划具有巨大的潜力，有助于开发加拿大独资拥有的几种先进材料技术，用于几个行业应用，特别是加拿大制造业。

This 5-year research program is concerned with the development, characterization, and property measurements of several groups of advanced electroformed and cold-sprayed materials that are currently not available elsewhere in the world. The first group is corrosion-resistant copper made by electroforming/cold spraying on the outer surface of Used Fuel Containers (UFCs) for safe and long-term storage (>1 million years) of radioactive waste generated by Canada's fleet of nuclear reactors in a deep geological repository (DGR). The construction of the DGR is expected to begin in 2033 and to become operational in the early 2040's. This part of our research program is a crucial component of a multi-researcher, multi-university research effort to study the long-term performance of the UFC in the expected DGR environment. The second type of material deals with the development of high strength and high temperature stable electroformed nanocrystalline alloys (Ni-Co, Co-P, and high-entropy alloys) that could find application in the aerospace or automotive industries. The last group of electroformed materials addresses superhydrophobic composite electroforms for application as advanced heat-transfer and corrosion-resistance materials for heat exchanger applications in Canada's power industries. Both the alloy and composite electroform work is expected to produce new materials in the medium time frame of 5-10 years. The research builds on previous successful material developments by the applicant and his research team in the areas of advanced nanocrystalline electrodeposits and grain-boundary-engineered materials. The program will be executed in strong collaboration with the Nuclear Waste Management Organization (NWMO, Toronto), the National Research Council (NRC, Boucherville) and Integran Technologies, Inc. (Mississauga). The research will contribute to the training of 19 highly qualified personnel (HQP) who will directly interact with several researchers at the collaborating external partners. This fundamental research program has great potential to contribute to the development of several advanced materials technologies that are wholly Canadian owned for several industry applications particularly for Canadian manufacturing industries.
