- 摘要:
- 摩擦是涉及数学、物理和材料学等学科的一门复杂的交叉学科。集成计算材料工程是将计算材料科学工具集成为一个整体系统并把设计和制造统一起来,可充分发挥其综合解决问题的优势,加速先进固体润滑材料的开发和优化工程设计的过程。本文从新材料研发的理论驱动范式出发,介绍了Prandtl-Tomlinson和Frenkel-Kontorova经典摩擦模型。应用这些模型,总结了本团队在原子尺度模拟计算中二维润滑材料的磨损及润滑机制方面的研究进展。从数据驱动的机器学习角度,通过分析润滑和耐磨损2种性能案例,综合人工智能在材料摩擦性能方面的研究逻辑和特点。基于新材料研发范式的逻辑,讨论集成计算材料工程在固体润滑领域的应用,突出集成多尺度计算模式对揭示结构超滑的机制具有重要意义。
Tribology research is a synthetic subject involving mathematics, atomic and molecular physics, materials science
and many other fields. Integrated computational materials engineering (ICME), which integrates computational materials
science, design and manufacture into a whole system, is beneficial for solving complex tribological problems and
accelerating the development of advanced solid lubricants and optimization of preparation process. In this review, beginning
with the theory-driven paradigm, both the Prandtl-Tomlinson and Frenkel-Kontorova models are introduced. Applying these
theories, the latest progress in the authors' team on two-dimensional lubricants by utilizing atomic scale simulations is
summarized. From the perspective of data-driven machine learning, the logical methods and advantages of artificial
intelligence in materials tribological performance are presented by analysing the cases of lubricity and wear-resistance
properties. Based on the frames of developing materials paradigms, the applications of ICME in tribology are discussed,
paving a path for developing advanced and engineering lubricants.
