利用差示扫描量热法评价润滑油的高温抗氧化性能

Evaluation of High Temperature Antioxidation Performances For Lubricants by Differential Scanning Calorimetry (DSC)

本文介绍了利用差示扫描量热法检测高温润滑油氧化诱导时间、起始氧化温度、沉积物形成趋势等指标的方法。利用差示扫描量热法对酯类润滑油及其抗氧剂的高温抗氧化性能进行了评价。

Differential scanning calorimetry (DSC) was introduced to determine high temperature lubricant' oxidation induction time, incipient oxidation temperature and deposit fowl tendency. The high temperature performances of a ester lubricant and one of its antioxidants were also evaluated.
