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

摘要

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.
