主 题：biodiesel low friction fatty acids tribochemistry surface analysis
摘 要：This paper investigates the effect of unsaturated fatty acid additives on the lubricating properties of a biodiesel,composed of a blend of fatty acid methyl esters(FAMEs)and a conventional diesel *** presence of fatty acids as additives for biodiesel improves their lubricating properties at elevated temperature *** formation of a protective lubricating tribochemical film on the steel contact surfaces has been *** temperature conditions and possibly oxygen are needed to form this film that reduces friction and limits *** analytical tools have revealed the insulating nature of the formed tribofilm and its chemical ***-induced reticulation is thought to play a major role in the growth of this insulating film.
