Abstract
This paper focusses on the effect of aluminium oxide nanoparticles concentration on tribological properties of lubricant oil and noise response on Detroit engine 92V friction parts. The nanomaterials were produced by sol-gel production, process. The manufactured nanomaterials and the tested part were evaluated by scanning electron microscope (SEM) analysis. The coefficient of friction (CoF) and noise response were studied. Results analysis illustrated that the addition of Al2O3 nanoparticles has improved the tribological properties of the lubricating oil and decreases the wear rate of engine parts according to the decrease of CoF. Adding 1% wt. of Al2O3 nanoparticles to oil has decreased the wear rate and the CoF more than 0.5% wt. of Al2O3 nanoparticles addition.
