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.

这项为期5年的研究计划涉及到几组先进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无法获得。第一类是通过电铸/冷喷涂在乏燃料容器（ufc）的外表面制成的耐腐蚀铜，用于安全长期储存（100万年）加拿大核反应堆机队在深地质储藏库（DGR）中产生的放射性废物。DGR的建设预计将于2033年开始，并于2040年初投入使用。我们的研究计划的这一部分是一个多研究人员，多大学的研究工作的重要组成部分，研究UFC在预期的DGR环境中的长期性能。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）的发展，可以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材料，可作为加拿大电力工业热交换器应用的高级传热和耐腐蚀材料。合金和复合电铸工作预计将在5-10年的中期时间框架内产生新材料。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的材料开发基础上。该项目将在核废料管理组织（NWMO，多伦多）、国家研究委员会（NRC, Boucherville）和Integran技术公司（Mississauga）的大力合作下执行。这项研究将有助于培训19名高素质人员（HQP），他们将直接与外部合作伙伴的几名研究人员进行互动。这个基础研究项目具有巨大的潜力，可以为加拿大全资拥有的几个先进材料技术的发展做出贡献，这些技术适用于几个行业，特别是加拿大制造业。
