Influence of the dispersion of nano titanium dioxide on the tribological performance of fabric self‐lubricating liner

Abstract

ABSTRACT Nanoparticles with unique properties have been widely used in various fields. The tribological performance of the fabric self‐lubricating liner, which is used as the main component of spherical plain bearings, directly affects the bearing service life. The purpose of this study was to prepare a self‐lubricating liner enhanced with nano titanium dioxide (nano‐TiO 2 ) by dispersion technology. The effects of several factors on the dispersion of nano‐TiO 2 were studied in detail. The effects of the dispersion of nano‐TiO 2 on the tribological properties of a self‐lubricating liner were analyzed comparatively. The best dispersing conditions were determined through experiments and statistical characterization. From the results of the tribological tests, the fabric self‐lubricating liner reinforced with nano‐TiO 2 showed better antifriction and wear‐resistant properties than that without nanoparticles. © 2013 Wiley Periodicals, Inc.
