英文摘要
In this research, we paid attention to the low friction which appeared when the sliding speed of diamond coating on a rotating metal disk was increased to 2-3 m/s. We solved the lubrication mechanism of this low friction by way of numerical simulation and showed that the diamond coating was floated by high pressure induced by micro/nano-scale gas flow between the diamond coating with micro/nano-scale surface structure and the counter metal surface. We also showed that this was a new phenomenon peculiar to micro/nano-scale gas flow.
