报告摘要

材料的性能以及各种表面与界面性质，在很大程度上取决于其电子行为。以往研究一直尝试将这些性能与量子力学描述的电子态联系起来，然而量子理论在复杂结构材料设计中通常难以操作。因此，需要一种简明但基本的参数来反映材料的电子行为，以指导材料分析与设计。在本报告中，电子功函数 （金属内部费米能级的电子移动到其表面的最小能量）将被显示是一种携带“类基因” 信息可用于分析材料，指导材料设计和表面/界面调控的基本参数。报告将论证电子功函数与材料以及其表面/界面性质之间的相关性，并探讨基于电子功函数的材料设计方法，即“类基因材料工程”的电子冶金框架及其在力学性能、磨损与腐蚀等领域的应用潜力。

报告题目：High-/Medium-Entropy Alloys and Wear-Resistant Coatings for Extreme Tribocorrosion Environments

报告人：刁贵江 博士（加拿大阿尔伯塔大学）

报告人简介

Guijiang Diao is a Research Scientist and Postdoctoral Fellow at the University of Alberta, working under the supervision of Prof. Dongyang Li, a Fellow of the Canadian Academy of Engineering. He specializes in high- and medium-entropy alloys, lightweight Al-based medium-entropy alloys, and advanced wear-resistant coatings for extreme environments. His work focuses on the critical role of matrix–reinforcement chemical compatibility in microstructural evolution, as well as composition-driven regulation of mechanical properties and corrosion–wear synergistic behavior. He pioneered a strategy for transforming brittle Al3Ti into a ductile and thermally stable lightweight medium-entropy alloy, and developed a cost-effective hard coating featuring columnar Cr2B phases integrated with a dispersed carbide network. As a core researcher, he has contributed to major NSERC and industry-sponsored projects, including high-entropy alloys for small modular reactors and ML/DFT-assisted materials design. He has published more than ten first-author papers in leading journals such as Acta Materialia and Wear, and has delivered multiple oral presentations at the Wear of Materials (WOM) conference. These achievements demonstrate his strong expertise and promising potential in advancing wear-resistant materials and high- and medium-entropy alloy technologies.

报告摘要

To address the premature failure of flow components in the energy and chemical industries under combined abrasive, adhesive, and corrosive wear, this report establishes a design paradigm for high- and medium-entropy alloys and coatings through the sequence of “composition design → microstructure control → strength–toughness synergy → tribocorrosion enhancement.” It highlights interstitial alloying and in situ carbide formation in Ni-, Fe-, and AlCrFeNi(Ti)-based systems to regulate FCC, L21, A2, and B2 phase constituents as well as nanoprecipitates, thereby alleviating the trade-offs among strength, toughness, and wear resistance. Lightweight Al3Ti-based high- and medium-entropy alloys enabled by the D022-to-L12 structural transformation are shown to possess enhanced thermomechanical stability. In addition, a Cr2B-reinforced coating strategy is proposed to balance wear resistance and cost, together with evaluation protocols for corrosion–wear synergistic behavior. By integrating electron work function criteria with multiscale characterization, this work bridges laboratory-scale synthesis and industrial application, providing guidance for material selection and design in extreme service environments.
