BORON NITRIDE NANOSHEET SURFACE REINFORCEMENT OF ALUMINUM

Abstract

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.
