THE EFFECT OF ADDITION OF NANOPARTICLES, ESPECIALLY ZRO2-BASED, ON TRIBOLOGICAL BEHAVIOR OF LUBRICANTS

The aim of the paper was to discuss different effects, such as, among others, agglomeration of selected nanoparticles, particularly those from zirconia, on the tribological behavior of lubricants.The explanation of the difference between the concepts of ‘aggregation’ and ‘agglomeration’ for ZrO2 nanoparticles is included.The
