چکیده انگلیسی
Engine valve train wear protection has been observed despite the absence of classical tribofilm formation. This was found with a lubricant containing zinc dialkyldithiophosphate (ZDDP), despite conventional understanding that ZDDP reduces wear by forming a thick, protective, inorganic phosphate tribofilm. We suggest that an antiwear additive can function by forming non-adherent triboproduct via a mechanically-stimulated chemical reaction. This triboproduct provides antiwear performance while entrained in the contact and is eventually expelled. In a reciprocating sliding tribometer it is observed as a pile of debris on the side of the contact.
