润滑油氧化安定性评价方法及与PDSC的相关性研究

摘要

润滑油氧化安定性是决定润滑油使用寿命的主要指标之一。氧化安定性的评价方法多种多样,大致可分为氧化管试验法、旋转氧弹法和PDSC法三大类。氧化管试验法和旋转氧弹法是两类经受了长期的实践检验的模拟试验方法。PDSC是一种热分析方法,在润滑油氧化安定性研究中用途日益广泛,本文评述了其与氧化管试验法和旋转氧弹试验法之间的比较研究现状。%The oxidation stability of lubricant oil is one of the critical factors deciding the service time of the oil. There are many kinds of evaluation method of the .oxidation stability of lubricant oil that can be classified into three species including oxidation tube tests, rotary pressure vessel method and PDSC. Oxidation tubes tests and rotary pressure vessel method are the two species of long-time tested simulated methods. PDSC is a thermal analysis method used in the oxidation stability of lubricant oil, it is a kind of evaluation method that is more and more widely used. It is discussed in this paper that situation of relativity of PDSC and the others two.
