Tribological Properties of WS2 Nanoparticles Lubricants on Aluminum-Silicon Alloy and Carbon Steels
Keywords:Lubricating oil, anti-wear and friction, nanoparticles, tribological chemistry, piston
The rheological properties of nanometric tungsten disulphide (WS2) nanoparticles oil lubricants and its tribological performance with two hypereutectic Al-Si alloy and carbon steel are examined. These two oils are used to reduce wear and friction and to explore the actions via tribological pin-on-disk tests. The pin was made from hypereutectic Al-Si alloy on steel disk, taking into consideration the effect of loads (10, 20, 30 N) and different speed (200, 300, 400 rpm). Oils with and without WS2 nanoparticles reveal the loss rate due to friction. The results show that WS2 nanoparticles oil-dispersed lubricants are capable of reducing wear, improved by a mechanism which was characterized not only by the viscosity of the WS2 nanoparticles suspensions but also the promotion of contact’s surface as combined anti-corrosion, as well as effective reduction of friction on the surface film. Therefore, a lubricant added to nanoparticles can protect the piston surface.
