An Ultrahigh Vacuum Investigation of the Chemistry and Tribology of Extreme Pressure Lubricant Additives

在分析和表面化学项目的支持下，Tysoe教授和他在威斯康星大学密尔沃基分校化学系的同事正在研究极压润滑的分子机制，使用超高真空光谱探针和销盘摩擦学测量的组合。 含磷和硼的润滑剂添加剂的作用是检查良好表征的铁和铝表面。 对这些极压条件下表面化学的分子水平理解将有助于设计改进的添加剂，对金属加工和汽车工业产生重大影响。 与工业润滑油制造商的密切联系扩大了这项工作的教育和更广泛的影响。威斯康星大学密尔沃基分校的Tysoe教授和他的团队使用传统的针盘摩擦测量，在使用电子光谱探针表征的表面上，正在探索含硼和磷的润滑剂添加剂存在下的极压润滑机制。 了解这一过程的分子机制，可以设计出在金属加工行业具有重大影响的改进型润滑剂添加剂。

With the support of the Analytical and Surface Chemistry Program, Professor Tysoe and his coworkers in the Department of Chemistry at the University of Wisconsin-Milwaukee are investigating the molecular mechanism of extreme pressure lubrication, using a combination of ultra high vacuum spectroscopic probes and pin on disc tribology measurements. The role of phosphorous and boron containing lubricant additives is examined on well characterized iron and aluminum surfaces. A molecular level understanding of the surface chemistry under these extreme pressure conditions will enable the design of improved additives, with significant impact on the metal machining and automotive industries. Strong connections with industrial lubricant manufacturers extend the educational and broader impacts of this work. Using traditional pin on disc measurements of friction, on surfaces characterized using electron spectroscopic probes, Professor Tysoe and his group at the University of Wisconsin-Milwaukee, are exploring the mechanisms of extreme pressure lubrication in the presence of boron and phosphorous containing lubricant additives. Understanding the molecular mechanism of this process enables the design of improved lubricant additives with significant impact in the metal working industry.
