SBIR Phase I: Minimum Quantity Lubrication Delivered by Supercritical Carbon Dioxide for Forming Applications

该小型企业创新研究（SBIR）第一阶段项目旨在开发用于金属成形应用的下一代超临界二氧化碳（CO2）金属加工液（MWF）。 该方法是提供含有适当添加剂和超临界CO2的专用环保润滑剂，实现至少与目前使用的水基MWF一样好的工具磨损率、力和表面光洁度。 预计使用该技术将需要更少量的MWF。 该项目的更广泛/商业影响将是在金属成形应用中应用环境友好的MWF的潜力。 在任何时候，美国都有大约20亿加仑的MWF在使用，这是一个必须处理和补救的巨大废物流。 此外，MWFs对工人健康和安全的负面影响也令人严重关切。 这项技术可能会提高金属成形应用和相关行业的可持续性，改善工人的健康和安全。

This Small Business Innovation Research (SBIR) Phase I project aims to develop next generation supercritical carbon dioxide (CO2) metalworking fluid (MWF) for metal forming applications. The approach is to deliver specialized environmentally-friendly lubricants containing appropriate additives 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 broader/commercial impact of this project will be the potential to enable the application of environmentally-benign MWFs in metal forming applications. 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. Moreover, the negative effects of MWFs on worker health and safety are also of serious concerns. This technology may lead to increased sustainability and better worker health and safety in metal forming applications and relevant industries.
