The use of carbon lubricants with different morphologies in boron oil on tribological performance of ALSi16 alloy

This study examined the impact of carbon-based lubricants, utilized as solid lubricants to reduce material wear rates. Graphite, carbon nanotubes, and two hydrothermal carbons were incorporated into boron oil to prepare colloidal suspensions for this objective. To evaluate the concentration effect, three different ratios of each carbon lubricant were used. AlSi16 alloy, which is frequently exposed to wear in a range of application areas, was used as the substrate material in wear studies. There was a detailed discussion of the wear processes and the results. These discussions showed that smaller particle shapes produced better results and that the wear rate of the substrate material decreased as the carbon lubricant content increased. It was found that the wear rate of the AlSi16 substrate material was reduced by more than 70% when carbon nanotubes and two hydrothermal carbons (0.2 weight percent) were used.
