Abstract Scope |
Nanostructured metallic multilayers (NMMs) are emerging materials with excellent physical, mechanical, and tribological properties. Extensive previous research highlights the fact that novel deformation physics control plasticity in the NMMs when the individual layer thickness are confined to a few nanometers. In this work, the nanomechanical and tribocorrosion properties of the Al-based NMMs were studied. Nanoindentation and nanowear tests show that the hardness and wear resistance of Al/X mutlilayers strongly depends on the individual layer thickness and the other constituting material. The corrosion and tribocorrosion resistance of Al-based NMMs were evaluated through potentialdynamic polarization experiments and tribocorrosion tests under open circuit potential in simulated seawater respectively. The results reveal that the complex synergistic effects of mechanical deformation and corrosion cause very diverse tribocorrosion behavior of different NMMs. These understandings provide a good basis for material selection and design strategy of NMMs for use under complex environment. |
