05.10.2018 F. Xavier Borras 456 Views

Every second year the EDF-PPRIME Workshop is dedicated to sealing technology. This week the 17th edition of this event was held at the EDF Lab Paris-Saclay focusing on minimizing both leakage and friction of rotary […]

Antiwear tribofilm growth - AFM study

14.03.2016 275 Views

In a wide range of tribological components, the lubricant is not capable of separating the surfaces and areas of metal-to-metal contact occurs. However, the metal-to-metal contact area can be minimized by the action of additives, [...]
