Abstract

In this work, molecular dynamics simulations were conducted to investigate deposition behavior of composite graphene nanoplatelets (GNPs)-Ni particles at various velocities and with different graphene contents. The results indicated that GNPs impede plastic deformation of the metallic particle and stress transfer to it, simultaneously limiting metallurgical bonding at the interface with the substrate. The particle/substrate bonding mechanism was a combination of metallurgical bonding and van der Waals forces physisorption, with the metallurgical bonding playing the primary role in adhesion strength. Increasing the impact velocity and decreasing the GNP content, both resulted in a larger area of metallurgical bonding, thereby enhancing the bonding strength. The particle/particle adhesion involves lateral and interlayer connections among GNPs, activating additional mechanical interlocking between the adjacent particles. Subsequent impact of the upcoming particles tamped the previously deposited one, leading to densification effect. These results deepen our comprehension of how graphene nanoplate-metal composites form.

期刊介绍： Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
