摘要: The rheological properties of nanometric tungsten disulphide (WS 2 ) nanoparticles oil lubricants and its tribological performance with two hypereutectic Al-Si alloy carbon steel are examined. These oils used to reduce wear friction explore the actions via pin-on-disk tests. pin was made from on disk, taking into consideration effect loads (10, 20, 30 N) different speed (200, 300, 400 rpm). Oils without WS reveal loss rate due friction. results show that oil-dispersed capable reducing wear, improved by a mechanism which characterized not only viscosity suspensions but also promotion contact’s surface as combined anti-corrosion, well effective reduction film. Therefore, lubricant added can protect piston surface.
