In this work, 1,3-diketone synthesized via the Claisen condensation method and nano-copper particles modified by Brust–Schiffrin were added into a commercial marine medium-speed diesel engine cylinder piston oil to evaluate their effects on boundary lubrication performance. Friction wear tests conducted CKS-coated ring cast-iron liner samples demonstrated significant reductions in both friction with addition of particles. Compared original without additives, force was reduced up 16.7%, while decreased 21.6% 15.1% at 150 °C, respectively. A worn surface analysis indicated that functionalized influenced depolymerization tribo-chemical reactions anti-wear additive ZDDP (zinc dialkyldithiophosphate) oil. This modification enhanced oil’s anti-friction properties, offering valuable insights development eco-friendly lubricants for energy-efficient systems.
