A type of nitrogen-oxygen modified rapeseed oil(NOR),a new environmentally friendly lube additive,was synthesized and the chemical structure was characterized by infrared spectrum.The effects of the rapeseed oil containing NOR additive on the friction and wear behavior of steel-steel and steel-aluminum alloy systems were investigated with a four-ball machine and an Optimol SRV friction and wear tester respectively.The morphographies of the worn surfaces were analyzed by means of scanning electron microscopy(SEM).At the same time,the worn surfaces of the 2024Al alloy block were analyzed by means of X-ray photoelectron spectroscopy(XPS) and the tribological mechanism of nitrogen-oxygen modified rapeseed oil was studied.The results showed that the type of modified rapeseed oil as additives can obviously decrease the wear rate and friction coefficient of steel-steel friction pair and steel-aluminum friction pair.Its lubrication mechanism is inferred that a high strength adsorption film and/or tribochemistry reaction film is formed on the worn surface of the Al alloy due to the carrier effect of a long chain rapeseed oil,high reaction activities of nitrogen and their synergisms.

对菜籽油进行化学改性制备了一类氮氧型改性菜籽油添加剂(NOR),并利用红外光谱对其主要官能团进行鉴定。分别通过四球和SRV摩擦磨损试验机考察了以菜籽油为基础油,以NOR为添加剂时对钢-钢摩擦副和钢-铝摩擦副抗磨减摩性能的影响,用扫描电子显微镜观察分析钢球磨斑表面的形貌,同时通过对铝合金磨痕进行X射线光电子能谱分析,探讨了氮氧型改性菜籽油润滑添加剂的抗磨减摩机理。结果表明:以氮氧型改性菜籽油为添加剂,以菜籽油为基础油时,钢-钢摩擦副和钢-铝摩擦副均表现出良好的抗磨减摩作用,其润滑作用机理是由于长链菜籽油分子的载体作用、氮的高反应活性以及二者的协同作用在金属摩擦表面形成了含氮、氧及碳等元素的表面保护膜。
