Abstract The awarded instrumentation allows for a modernized integrated approach to research and education of important tribological issues. The science of tribology involves interacting surfaces and therefore includes areas such as surface roughness, friction, wear and lubrication. Tribology is highly important for increasing the efficiency of modern machinery, as the estimated tribological losses in the United States are near 6% of its gross national product. In response, tribology has received much needed attention in recent decades. Integrating research and education of tribological issues is the next step needed to greatly increase awareness of the role of tribology for improving the energy efficiency of modern machinery. The development of a tribological research facility at Loyola Marymount University takes this next step. The three main equipment components that allow for the development of a relatively comprehensive tribological research facility are: 1) ADE PhaseShift MicroXAM white-light interferometer, 2) CETR Micro-Tribometer (UMT) high-temperature module and 3) COY atmospherically controlled glove box. Each of these components is critical in different aspects and will combine to form the tribological research facility. The interferometer allows for complex analyses of surface features and is crucial for both the research and educational aspects of the research facility. This component is necessary for investigating worn surfaces and illustrating the importance of surface design for improving efficiency. The interferometer is crucial for the further development of a generalized abrasive wear law through its capacity to quantify the abrasive wear volume of a test specimen with high precision. In addition, this equipment allows for the direct investigation of the importance of surface structures by undergraduate engineering students. The CETR tribometer high-temperature module allows for high temperature tribological research using an existing CETR tribometer, which is important for simulating the tribology of practical applications under high temperatures. This component allows for investigating the possibility of decreasing petroleum usage by using bio-based lubricants such as soybean oil, peanut oil, etc., as well as re-recycled petroleum based lubricants. Such studies are necessary to facilitate a decreased dependence on imported petroleum. Finally, the glove box allows precise atmospheric control of tribological testing conditions. The glove box will allow for both research and educational comparative studies directly relating friction and wear to specific atmospheric conditions, including humidity and the absence of certain gases.Broader impactsThe awarded equipment provides direct integration of scientific education and research of a highly important issue. The instrumentation will directly impact the scientific education of approximately 30 students per year, approximately 27% of which are underrepresented minority students, 45% of which are women and 17% of which are Asian students. Through an awareness of the importance of tribology, future engineers and scientists will have the necessary background to adequately deal with issues involving increasing energy efficiency through proper tribological design. Intellectual meritThe equipment will educate engineering students about the importance of surface engineering by providing hands-on experience of tribological topics covered in upper-level theoretical engineering design coursework. In addition, the tribological research facility will provide more extensive research opportunities for the faculty, as well as both graduate and undergraduate students. The tribological research facility will significantly raise the intellectual capacity of the school for high-level research.

摘要获奖的仪器允许一个现代化的综合方法来研究和重要的摩擦学问题的教育。摩擦学涉及相互作用的表面，因此包括表面粗糙度，摩擦，磨损和润滑等领域。摩擦学对于提高现代机械的效率非常重要，因为美国的摩擦损失估计接近其国民生产总值的6%。因此，摩擦学在近几十年来得到了急需的关注。整合摩擦学问题的研究和教育是下一步需要大大提高对摩擦学在提高现代机械能效方面作用的认识。洛约拉玛丽蒙特大学摩擦学研究设施的发展迈出了下一步。三个主要的设备组件，允许开发一个相对全面的摩擦学研究设施是：1）ADE相移MicroXAM白光干涉仪，2）CETR微摩擦（UMT）高温模块和3）COY大气控制手套箱。这些组件中的每一个在不同方面都是至关重要的，并且将联合收割机结合起来形成摩擦学研究设施。干涉仪允许复杂的表面特征分析，对于研究设施的研究和教育方面都至关重要。该组件对于研究磨损表面和说明表面设计对提高效率的重要性是必要的。该干涉仪是至关重要的广义磨料磨损规律的进一步发展，通过其能力，以高精度量化的测试试样的磨料磨损体积。此外，该设备允许工程专业本科生直接调查表面结构的重要性。CETR摩擦试验机高温模块允许使用现有的CETR摩擦试验机进行高温摩擦学研究，这对于模拟高温下实际应用的摩擦学非常重要。该组分允许研究通过使用生物基润滑剂如大豆油、花生油等来减少石油使用的可能性，以及再循环的石油基润滑剂。这种研究对于减少对进口石油的依赖是必要的。最后，手套箱允许摩擦学测试条件的精确大气控制。手套箱将允许研究和教育的比较研究直接相关的摩擦和磨损的具体大气条件，包括湿度和某些气体的情况下。更广泛的影响获奖设备提供了一个非常重要的问题的科学教育和研究的直接整合。该仪器将直接影响每年约30名学生的科学教育，其中约27%是代表性不足的少数民族学生，其中45%是女性，17%是亚洲学生。通过认识摩擦学的重要性，未来的工程师和科学家将有必要的背景，以充分处理涉及通过适当的摩擦学设计提高能源效率的问题。该设备将通过提供高级理论工程设计课程中所涵盖的摩擦学主题的实践经验，教育工程专业的学生了解表面工程的重要性。此外，摩擦学研究设施将为教师以及研究生和本科生提供更广泛的研究机会。摩擦学研究设施将显著提高学校的高水平研究的智力能力。
