Interaction between Lubricants Containing Phosphate Ester Additives and Stainless Steels
One way to improve fuel efficiency in today’s jet aircraft engines is to create an environment for higher operating temperatures and speeds. New and improved lubricants and bearing materials must be developed to remain stable in these elevated operating temperatures. Three lubricants, with varying amounts of tricresyl phosphate added as an anti-wear/extreme pressure additive were tested on two ...
متن کاملTowards Phosphorus Free Ionic Liquid Anti-Wear Lubricant Additives
The development of improved anti-wear additives would enable the use of lower viscosity oils that would lead to improved efficiency. Ionic liquids have the potential to be this type of new anti-wear additive. However, currently the best performing ionic liquids that are miscible in non-polar base oils, the phosphonium phosphates, contain phosphorus on both the cation and anion. Manufacturers ar...

متن کاملExposure to triaryl phosphates: metabolism and biomarkers of exposure.
The leakage of tricresyl phosphate-containing engine lubricants into aircraft cabin air, either from worn or defective engine seals or under normal operating conditions, is a serious concern for both the health and safety of the cabin occupants, since the oil contains one to five percent tricresyl phosphate (TCP) esters, known neurotoxins. The exposure of pilots is a particular concern since th...
متن کاملThe Wear Effects and Mechanisms of Soot Contaminated Automotive Lubricants
A study has been carried out to investigate the influence of soot contaminated automotive lubricants in the wear process of a simulated engine valve train contact. Previous research on this topic has been mainly performed from a chemical point of view in fundamental studies, with insufficient relevance to real engine conditions i.e. load and geometry. This study investigates the conditions unde...
