Extreme pressure (EP) and antiwear (AW) additives are necessary for boundary lubrication.
However, their mechanisms and physical and chemical properties remain unclear. EP and …

Molybdenum dialkyl dithiophosphate (MoDDP) and potassium borate (PB) were selected as
additives for the greases. Results show that the polar MoDDP additive cause grease …

Vegetable oil–based bio-lubricants possess potential as an alternative to mineral oil–based
lubricants due to their biodegradability and renewability. However, a detailed examination of …
