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

在分析和表面化学计划的支持下，威斯康星大学密尔沃基分校化学系的Tysoe教授和他的同事们正在使用超高真空光谱探头和销盘摩擦学测量相结合的方法来研究极端压力润滑的分子机制。研究了含磷和含硼的润滑剂添加剂在特性良好的铁和铝表面上的作用。在分子水平上了解这些极端压力条件下的表面化学将使改进添加剂的设计成为可能，并对金属加工和汽车行业产生重大影响。与工业润滑油制造商的紧密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销盘摩擦测量方法，在使用电子光谱探针表征表面的情况下，探索在含有硼和磷的润滑油添加剂存在的情况下，极压润滑的机理。了解这一过程的分子机理使改进的润滑油添加剂的设计在金属加工业中具有重大影响。

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.
