Influence of the Nanoclay Concentration and Oil Viscosity on the Rheological and Tribological Properties of Nanoclay-Based Ecolubricants

This manuscript describes a rheological and tribological study carried out on eco-friendly lubricants. These ecolubricants were made up of nanoclays as dispersed phase (a layered nanosilicate (montmorillonite Cloisite 15A) fiber-like nanoclay (sepiolite Pangel B20)) vegetable-based oil continuous (castor (CO), high oleic sunflower (HOSO) their mixtures). A series nanoclay-based prepared by varying both concentration base oil, thus, its viscosity. Friction wear behaviors assessed using ball-on-three plates tribometer cell. The results showed that the sepiolite B20 yielded an important reduction in scar diameter, thus revealing potential anti-wear load-carrying additive ecolubricant formulations, while 15A proved to have friction improving properties. reducing properties found be influenced
