Efficient Tribology Testing of Lubricating Oils with Nano-Additives

The following solutions have been utilized to overcome common scatter of tribology test data: Perform tests at various well-controlled sliding-to-rolling, speed-to-load and temperature levels. Obtain Stribeck curves in a wide range of loads and speeds, so that to identify test conditions of boundary, mixed and hydrodynamic lubrication. For evaluation of the coefficient of friction, monitor both its friction force and normal load components. For wear evaluation, monitor its dynamics and then separate its running-in and stable components. Monitor contact acoustic emission and electrical resistance to detect formation and destruction of tribo-films, initiation and propagation of wear.
