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.

在分析和表面化学计划的支持下，威斯康星大学 - 米尔沃基大学化学系教授及其同事正在研究极高压力润滑的分子机制，结合了超高的真空镜头探针和PIN在椎间盘摩擦学测量上。 在特征良好的铁和铝表面上检查了含有润滑剂添加剂的磷和硼的作用。 在这些极端压力条件下，对表面化学的分子水平的理解将能够设计出改进的添加剂，并对金属加工和汽车行业产生重大影响。 与工业润滑剂制造商的牢固联系扩展了这项工作的教育和更广泛的影响。 Tysoe及其小组在威斯康星大学 - 米尔沃基分校的摩擦表面上使用传统的PIN进行摩擦测量，在表面上，他的小组正在探索在硼龙和含有润滑剂添加剂的存在下极高压力润滑的机制。 了解这一过程的分子机制可以设计改进的润滑剂添加剂，并在金属工作业中产生重大影响。
