摘要

氮化硼纳米片(BNNS)是一种具有优异力学性能的类石墨烯结构，是设计新型纳米复合材料最有前途的增强元件之一。在此，我们通过分子动力学模拟研究了BNNS对铝基体表面增强的作用。结果表明，氮化硼纳米片涂层提高了材料的临界屈服强度、硬度和弹性模量。随着氮化硼层数的增加，强化效果更加显著。同时，系统温度越高，界面能越低，BNNS/Al体系的力学性能越弱。

BORON NITRIDE NANOSHEET SURFACE REINFORCEMENT OF ALUMINUM

The boron nitride nanosheet (BNNS), a graphene-like structure with excellent mechanical properties, is one of the most promising candidates for a reinforcement element to design innovative nanocomposites. Herein, we have investigated the BNNS, which serves for surface enhancement of the aluminum matrix via molecular dynamics simulations. The results show that the boron nitride nanosheet coating enlarges the critical yield strength, hardness, and modulus of elasticity. With an increase in the number of boron nitride layers, the strengthening effect is more significant. Meanwhile, a higher system temperature degrades the interfacial energy and weakens the mechanical properties of the BNNS/Al systems.
