This project is proposed to the NSERC - Mitacs Accelerate program for developing a new class of superior wear-resistant materials for protective surface layers, e.g., hardfacing overlays and coatings, in the form of composite which consists of a high-entropy alloy (HEA) matrix and complex carbides. The new overlays and coatings will be used to resist severe wear encountered in different sectors of Canada's energy industry, including oil sands, hydrogen fuel, hydroelectricity, wind energy, and coal mining. Wear can cause malfunction or failure of operation facilities, leading to high operation costs, short service life of facilities, and safety issues. The currently used overlays and coatings, e.g., WC/Ni alloy and WC/Co, have played an important role in protecting industrial facilities from wear attacks. However, these overlays and coatings have shortcomings, e.g., low wear resistance of the matrix materials, which are also prone to corrosion and thus less durable against wear in corrosive environments. This project is oriented to the development of a new generation of protective overlays/coatings, which consist of a high-entropy alloy (HEA) - matrix and complex carbides to resist severe wear in harsh operation conditions and aggressive environments, encountered in various sectors of energy production. The main outcomes will include prototype materials for commercial applications, guidelines for overlay/coating design, databases and standard for applications and further development. Minimizing wear of operation facilities, e.g., oil sands mining, will not only increase the competitiveness of Canadian oil industry in the global fuel market, but also promote clean energy production such as increased hydrogen production with lowered cost [extract hydrogen from oil sands (bitumen)], increased electricity production through the combustion of cheaper fossil fuels to power steam turbines, and improved efficiency of wind power production as well. This helps increase the clean energy utilization with reduced direct use of fossil fuels, helping minimize greenhouse gas emissions. The success of this project would have impact on the Canada energy industry and bring in significant benefits to Canadians in various aspects.

该项目是向NSERC-MITACS加速程序提出的，用于开发一种新的抗磨损材料，用于保护表面层，例如，以高凝集合金（HEA）基质和复杂的碳化物组成的复合材料形式，以固定的覆盖和涂料为组成。新的覆盖层和涂料将用于抵抗加拿大能源行业不同部门遇到的严重磨损，包括油砂，氢燃料，水力发电，风能和煤炭开采。磨损会导致操作设施故障或失败，导致高运营成本，设施的使用寿命短以及安全问题。当前使用的覆盖层和涂料，例如WC/NI合金和WC/CO，在保护工业设施免受磨损攻击方面发挥了重要作用。但是，这些叠加层和涂层存在缺点，例如，基质材料的低磨损耐药性，它们也容易腐蚀，因此在腐蚀性环境中耐用的耐用性较低。该项目面向新一代的保护性覆盖/涂料的发展，该保护性覆盖物/涂料由高渗透合金（HEA） - 基质和复杂的碳化物组成，可抵抗在恶劣的操作条件和激进的环境中，在能源生产的各个部门都遇到了严重的磨损。主要结果将包括用于商业应用程序的原型材料，覆盖/涂料设计指南，数据库和应用程序和进一步开发的标准。最大程度地减少运营设施的磨损，例如油砂开采，不仅会提高加拿大石油行业在全球燃料市场中的竞争力，而且还可以促进清洁能源生产，例如增加成本降低的氢产量（从油基（沥青）提取氢（沥青），通过更便宜的化石燃料燃料的燃烧来增强蒸汽涡轮机和富有效率的效率，从而提高了电力生产（沥青（沥青））。这有助于通过减少化石燃料的直接使用来增加清洁能源的利用率，从而有助于最大程度地减少温室气体排放。该项目的成功将对加拿大能源行业产生影响，并在各个方面为加拿大人带来巨大的好处。
