英文摘要	Purpose - the purpose of this paper is to investigate the hydrolytic stability of several s-hydroxethyl n,n-dialkyl dithiocarbamate-derived borates snb1, snb2, and snb3, to evaluate their tribological performances used as additives in polyalpha olefins (pao), and to explore the tribochemical action mechanism. design/methodology/approach - first, the three additives are synthesized and characterized. second, the hydrolytic stabilities of the three compounds are investigated. as the third step, they are, respectively, added to pao and a series of samples with different concentrations of the additives in pao are prepared, respectively. their tribological properties are evaluated with two types of four-ball machines, and then the wear scars were observed using a jsm-5600lv scanning electron microscope. finally, the elements on the worn surface are analyzed with a x-ray photoelectron spectroscope (xps). findings - the three novel compounds possess relatively good hydrolytic stabilities, excellent anti-wear (aw) performances, friction reduction properties, and load-carrying capacity. there is an optimum concentration of each of the three additives for their aw properties. according to the xps analytical results, a boundary lubrication protective film has formed during friction consisting of feso(4) film, fe(2)o(3) film, and the complicated adsorption film composed of n-containing organic compounds. in the protective films, a large quantity of compounds containing element b is not found. research limitations/implications - the antioxidation performances and the anticorrosion properties are not estimated. practical implications - three novel aw/extreme pressure (ep) additives are synthesized, and may be they have the potential industrial application as aw/ep additives in lubricating oil. originality/value - the present work provides a research method of n,s-containing organic borates as lubricating oil additives.
