This Small Business Innovation Research (SBIR) Phase II project aims to develop next-generation supercritical CO2 metalworking fluid (MWF) technology for highly demanding metal forming applications. The approach is to deliver specialized environmentally-friendly lubricants with supercritical CO2, achieving tool wear rates, forces, and surface finish at least as good as aqueous-based MWFs that are currently in use. It is anticipated that a much smaller amount of MWFs will be required with this technology. The formulation of new supercritical MWFs and the optimization of flowrates of oil and CO2 for metalworking processes will be studied. The patented supercritical CO2 system (so-called CHiP Lube) will be evaluated in real industrial settings to confirm its capability to replace current MWFs. The effectiveness and efficacy of CHiP Lube system will also be scaled and applied to other common industrial metal working processes such as rolling, extruding, and cutting.The broader/commercial impacts of this project will be the potential to provide an environmentally-benign lubricant system as an alternative to conventional MWFs with equal or better performance and lower cost. At any given time, approximately 2 billion gallons of MWFs are in use in the U.S.A. This represents a massive waste stream that must be treated and remediated. Plus, the negative effects of MWFs on worker health and safety are well documented. The components of CHiP Lube are naturally occurring and used in extremely low quantities. Therefore, the waste treatment and worker health concerns are minimized. CHiP Lube has been demonstrated in simple metal removal applications as providing lower tool wear and/or higher machining speeds than conventional MWFs, thereby leading to a lower overall cost of manufacturing. In addition, no carbon dioxide will be produced to run the process, as the CO2 used in the process will be recovered from other industrial processes such as ammonia and ethanol production.

这项小型企业创新研究（SBIR）II期项目旨在开发下一代超临界二氧化碳金属加工流体（MWF）技术，用于高度要求的金属形成应用。该方法是通过超临界二氧化碳，实现刀具磨损率，力和表面饰面至少与目前正在使用的水性MWF一样好，以提供具有超临界二氧化碳的专业环保润滑剂。 预计该技术将需要少量的MWF。 将研究新的超临界MWF的制定以及用于金属加工过程的油和二氧化碳流量的优化。将在实际工业环境中评估获得专利的超临界二氧化碳系统（所谓的芯片润滑油），以确认其替代当前MWF的能力。芯片润滑油系统的有效性和功效也将缩放并应用于其他常见的工业金属工作过程，例如滚动，挤出和切割。该项目的更广泛/商业影响将有可能提供环境繁制的润滑剂系统，以替代常规MWF，以相等或更好的性能和更高的成本和更高的成本和更低的成本。在任何给定的时间，美国都在使用大约20亿加仑的MWF。这代表了必须对其进行处理和修复的大规模废物流。另外，MWF对工人健康和安全的负面影响已得到充分记录。芯片润滑油的成分是天然发生的，并且数量极低。因此，废物治疗和工人健康问题被最小化。与传统的MWF相比，在简单的金属拆卸应用中已证明了芯片润滑油，从而提供了较低的工具磨损和/或更高的加工速度，从而导致制造总成本较低。此外，不会生产二氧化碳来运行该过程，因为该过程中使用的二氧化碳将从其他工业过程（例如氨和乙醇生产）中回收。
