Micro/Nano-Texture Design for Improving Tribological Properties of DLC-IL Composite Films
In the present paper, a new synergy lubricating system including both of surface morphology and chemical modification was presented to improve the tribological performances of DLC film. DLC-IL composite films with well-defined micro/nano-textures were produced by the combination of ICP technology, magnetron sputtering process and dip-coating method. At first, a two step method was used: silicon wafers were ICP patterned and subsequently DLC films were deposited on them. The second considered approach was the chemical modification of coated surfaces with IL film. In order to understand the lubrication mechanism of such functional surfaces, experimental research such as AFM, XPS, Raman, Nano-indentation and UMT-3 tests were carried out to investigate systemically the surface morphology, surface structure, chemical composition and mechanical properties of as-prepared DLC-IL composite films. Results showed that micro/nano-patterned DLC-IL composite films used special micro/nano-textures and surface chemical modification to construct the functional surfaces to achieve the super tribological performance. DLC-IL textured film with dense dimples and further chemically modified with IL monolayer showed significantly enhanced micro/nano-tribological performance compared with DLC-IL textured surface with sparse dimples without chemical modification.
