摘　　要：航空润滑油在高温下产生结焦,这些结焦会分布于整个航空发动机润滑系统,使航空发动机的运行工况恶化,最终会对飞行安全产生不可预知的风险。针对某航空润滑油的高温结焦问题,采用元素分析及能谱分析等手段,对航空润滑油高温结焦产物的组成进行了分析。航空润滑油高温结焦产物是一种含有金属元素和非金属元素的杂化物,碳,氧,铝和铜元素是结焦的主体元素,随机出现的其他微量元素可能来源于添加剂和/或外界污染物。Coking of aviation lubricants occurs at high temperatures,which can be distributed throughout the entire lubrication system of aviation engines,deteriorating the operating conditions of aviation engines and ultimately posing unpredictable risks to flight safety.For the high-temperature coking problem of an aviation lubricant,the composition of high-temperature coking products of aviation lubricant was analyzed by means of elemental analysis and energy spectrum analysis.The high-temperature coking product of aviation lubricants is a kind of heterogeneous compound containing metallic and non-metallic elements.Carbon,oxygen,aluminum and copper are the main elements of coking,and a few other elements appearing randomly may be originated from additives and/or external pollutants.
