Nanoparticles can enhance lubrication through several mechanisms: - Rolling Effect: Spherical nanoparticles can act as tiny ball bearings, reducing friction between surfaces. - Repairing Mechanism: Some nanoparticles can fill in surface imperfections, creating a smoother surface and reducing wear. - Protective Coating: Nanoparticles can form a thin, durable coating on surfaces, providing long-lasting protection against wear and corrosion.
