Correlation between Nano-Mechanical and Macro-Tribological Properties of Tribofilms Derived from Organic Phosphoric Additives

Correlation between nano-mechanical and macro-tribological properties of the tribofilm derived from phosphoric additives was investigated. Macro friction test was performed at steel/steel contact under lubrication with poly-alpha olefin (PAO) containing these types of phosphoric additives; tricresyl...
