Overview

This study demonstrates improved tribological performance with CuO nanoparticles in lubricants, suggesting enhanced efficiency. Significant reductions in friction and wear were observed.

Key Points

  • The addition of CuO nanoparticles significantly improves tribological performance on AISI 52100 steel surfaces.
  • At 0.1 Wt.% concentration, the coefficient of friction decreased by approximately 65.94%, significantly enhancing lubrication efficiency.
  • Tribological tests were performed using a four-ball tribotester under ASTM D4172 B standards, ensuring reliable results.
  • Identifying an optimal CuO concentration may support the development of scalable lubricants for industrial applications.
