Preparation and Surface Modification ZnO Nano-Powder with Antifriction Properties

Abstract

In this work, the surface modified ZnO nano-powder is prepared by the method of the combination of direct precipitation and in situ surface modification. The prepared samples are characterized by the means of laser particle size analysis, scanning electron microscopy, X-ray diffraction analysis and Fourier transform infrared spectroscopy. In the tribological test, by adding the surface modified ZnO nano-powder, the friction coefficient and the wear scar diameter of lubricants can be significantly reduced. The powder plays a role in antifriction.
