摘要: Three additive materials for perfluoropolyalkylether-based high-temperature engine oils were studied, a bis-substituted dibenzothiazole, diphenyl ether and triphenyl phosphine. The focus of this work was to understand how the additives interacted with various surfaces provide either anticorrosion or antiwear activity. In case found form thick, protective layer on surface. served as another equally effective but failed demonstrate surface third compound, phosphine, break down at an inorganic polyphosphate which provided level both function.
