Overview

Randomized trial investigates wear reduction and surface stabilization in diesel engines using hybrid nano-lubricants, indicating enhanced efficiency.

Key Points

  • The aim is to explore how hybrid CuO–Al₂O₃ nano-lubricants can improve the wear resistance and surface stability at diesel engine interfaces.
  • Multi-scale characterization using wear analysis, Keyence microscopy, FESEM, AFM, and X-ray diffraction.
  • Assessment of tribological behavior and surface transformations in hybrid nano-lubricated systems.
  • Transition from material removal-dominated wear to tribofilm-mediated adaptation with hybrid nano-lubricants.
  • Reduction in surface roughness and improved morphology, with a stable tribofilm formation observed.
  • Hybrid system outperforms individual CuO and Al₂O₃ lubricants, supporting enhanced interfacial stabilization.
