Tribological Properties and Self-repairing Effect of Palygorskite/Copper Nanocomposites as Lubricating Oil Additive
Palygorskite/copper nanocomposites were prepared in order to study the friction behaviour and self-repairing effect of HT200 tribopair.The friction and wear behaviors of the lubricant oil containing 4wt% nanocomposites were evaluated on an MMU-10G abrasive-wear tester.Results indicated that the average size of nanoparticles is 200nm and nanoparticle disperses homogeneously.The nanocomposites significantly improve the anti-wear performance.Wear mass loss decreases 41.7%and 63.2% compared with nano-palygoeskite and no additive.SEM and EDX examination of worn surfaces show that the incorporation of nano-copper and nano-palygorskite promote the formation of enriched films which play beneficial role for improving the wear properties.
