    摘要:

    采用7种不同磨粒含量标准油样,通过选择合理的特征元素、测试参数和元素测试组合方案,按照0~1×10-4、1×10-4~5×10-4两种磨粒质量分数范围,分段建立包含标准曲线、分析流程的润滑油中磨粒的EDXRF光谱测试方法。应用建立的测试方法,对某柴油机润滑油进行跟踪监测,验证该方法的跟踪监测能力;以26个同型设备油样为对象,对该方法与原子发射光谱、PQ铁磁性颗粒分析仪分析结果进行比较。结果表明,建立的润滑油EDXRF光谱测试方法能够有效地监测润滑油中的磨损颗粒,特别是针对大的磨损颗粒有着特殊的优势。

    Abstract:

    Seven standard oil samples with different concentration levels of wear particles were applied to research the method of test wear particles in lubricant based on EDXRF spectroscopy.By selecting appropriate characteristic elements,test parameters and test combinations of elements program,the method of test wear particles in lubricant based on EDXRF spectroscopy was established in subsection according to two kinds of mass fraction range of wear particles at 0~1×10-4 and 1×10-4~5×10-4,which includes the establishment of standard curves and analysis flows.The established testing method was used to monitor a diesel lubricant,and the monitoring and tracking ability of the method was verified.The oil samples from twenty six of same type equipments were selected to carry out a comparative analysis of the established EDXRF spectroscopy method,and the atomic emission spectroscopy method and the PQ ferromagnetic particle analysis method.The results show the established EDXRF spectroscopy method can effective monitor wear particles in lubricating oil,and has a special advantage to large wear particles.
