| 英文摘要 | Surface gradient nanostructures can be implemented in metallic materials to offer outstanding resistance to sliding friction and wear, but their scratch resistance and underlying anti-scratch mechanisms remain unknown. In this study, the scratch behavior and linked structure modification of a gradient nanograined 316L stainless steel were investigated and compared to the coarse-grained and the nanograined counterparts. After a single high-load scratch, inhomogeneous nanostructures are formed ahead of the indenter in the coarse-grained and nanograined samples, predominantly leading to mechanical incompatibility, crack nucleation and subsurface peeling-off. By contrast, the gradient nanograined sample exhibits superior scratch resistance without surface and subsurface cracking, thanks to strain delocalization associated with stabilized gradient nanostructure during scratching. This work forges the links between scratch-induced microstructural origin and high scratch resistance for gradient nanograined materials under extremely high tribological stress. |
