The nanoparticles were penetrated in the wear region using suspensions prepared in distilled water and ethylene glycol environment. The wear experiments were performed under 30 N load and 20 rpm speed condition in 1000 m wear distance using the ball-on-plate method. The worn surfaces were analyzed with a three-dimensional profilometer, scanning electron microscope/energy-dispersive X-ray (EDX), and atomic force microscope (AFM) methods. According to the results, the colloidal dispersed nano-gold particles in ethylene glycol performed 28.85% better on reducing the surface roughness, 2.32% on reducing the weight loss, 4.85% on increasing the heat transfer, and 1.22% on reducing the friction coefficient than the nano-silver particles.eninfo:eu-repo/semantics/closedAccessnano-silvernano-goldcolloidal suspensionswear surfaceabrasionadhesionlubricant additiveslubricantsmixed lubricationnanotribologysurface fracture crackingwearArticle10.1115/1.40465702-s2.0-850865758578Q2142WOS:000544031000007Q3
