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.

这个为期 5 年的研究计划涉及目前世界其他地方无法获得的几组先进电铸和冷喷涂材料的开发、表征和性能测量。第一组是通过电铸/冷喷涂在废燃料容器 (UFC) 外表面制成的耐腐蚀铜，用于在深层地质处置库 (DGR) 中安全长期储存（>100 万年）加拿大核反应堆产生的放射性废物。 DGR 预计将于 2033 年开始建设，并于 2040 年代初投入运营。我们研究计划的这一部分是多研究人员、多大学研究工作的重要组成部分，旨在研究 UFC 在预期 DGR 环境中的长期性能。第二种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，这些合金可在航空航天或汽车工业中找到应用。最后一组电铸材料涉及超疏水复合电铸件，作为加拿大电力行业热交换器应用的先进传热和耐腐蚀材料。合金和复合材料电铸工作预计将在 5 至 10 年的中期时间内生产出新材料。该研究建立在申请人及其研究团队之前在先进纳米晶电沉积和晶界工程材料领域成功材料开发的基础上。该计划将与核废料管理组织（NWMO，多伦多）、国家研究委员会（NRC，布谢维尔）和 Integran Technologies, Inc.（密西沙加）密切合作执行。该研究将有助于培训 19 名高素质人员 (HQP)，他们将直接与外部合作伙伴的几位研究人员互动。该基础研究计划具有巨大的潜力，有助于开发多种先进材料技术，这些技术完全由加拿大拥有，可用于多种行业应用，特别是加拿大制造业。
