Rezumat:

Polyethylene was added to three mineral oils. The influence of polymer addition on the rheological and tribological behavior of lubricant was studied. Experimental data show that the polymer concentration added to the base oil plays an important role to obtain a maximum film thickness and/or to prevent wear in EHD contacts. The polymer forms an immobile film over the metallic surfaces, having a thickness close to the polymer coil diameter. This monomolecular film adsorbed on the solid surfaces improves the lubricant performances (film thickness, wear resistance or traction behaviour).
