摘要：

To clarify the low friction mechanism of B-DLC coating in PAO oil lubrication, we measured reflectance spectrum at friction area in-situ by reflectance spectroscopy. We obtained surface roughness of B-DLC coating, thicknesses and polarizability of transformed layer formed on bulk B-DLC coating during friction test by analyzing reflectance spectrum. We suggested that the increment of polarizability of transformed layer had an effect on increment of van der Waals force between transformed layer and PAO oil. By increasing van der Waals force, oil molecular adsorbed on transformed layer, and then friction coefficient of boundary lubricant area of B-DLC coating decreased.
