Development, characterization, and mechanisms of performance of new environmentally friendly metal working fluids.

轻质材料如钛和耐高温腐蚀材料如镍合金对汽车和航空航天工业的吸引力受到加工这种合金的困难的影响。这些合金的加工受到高温和粘附的困扰，这最终导致工具和加工合金的严重损坏。然而，机加工是金属零件生产的重要组成部分，即使是铸造零件也需要某种形式的机加工。虽然加工参数的操纵已被观察到提高工作工具的寿命，但它对减轻加工工具的粘附或磨损几乎没有影响。使用润滑剂和冷却剂（金属加工液）可以减少加工的难度。金属加工液已被证明对机加工过程至关重要，可控制温度、减少摩擦以及消除机加工区域的碎屑。然而，目前的金属加工流体波塞存在不利的环境问题，而其他提出的冷却技术并没有完全消除对这些流体的需要。因此，目前的润滑和冷却剂解决方案不能充分或有效地解决加工难加工合金的问题。解决这一问题的一个切实可行的方法是应用环境友好的金属加工液，这是本研究的基础。本研究将探讨几种环保型金属加工液及添加剂对轻合金切削加工的影响。从而允许引入对当前金属加工液具有上级润滑性的环境友好的替代品。除了巨大的环境优势外，由于加工工艺的改进，还将带来成本效益。它还将更好地了解环境友好型添加剂，金属加工液和加工过程的相互作用。最后，该项目的成果将提高加拿大航空航天和汽车公司的竞争力，提高制造商使用的工艺的质量和产量，同时对环境指标产生积极影响。

The appeal of lightweight materials like titanium and high temperature corrosion resistant materials like nickel alloys to the automotive and aerospace industries is marred by the difficulty involved in machining such alloys. The machining of these alloys is plagued by high temperatures and adhesion which eventually lead to severe damage of tools and the machined alloy. However, machining is an essential part of the production of metal parts, even cast parts require some form of machining. Although the manipulation of machining parameters have been observe improve the life of the work tool, it bears little influence on mitigating adhesion or wear of the machining tool. The difficulties of machining can be reduced by the employment of lubricants and coolants (metalworking fluids). Metalworking fluids have proven essential to the machining process, controlling temperature, reducing friction as well as eliminating debris from the machining zone. However, present metalworking fluids posse adverse environmental issues, while other proposed cooling techniques do not completely eliminate the need of these fluids. Therefore, current lubrication and coolant solutions do not adequately or efficiently solve the issue of working with difficult-to-machine alloys. A practical solution to this issue is the application of environmentally friendly metalworking fluids, which is the basis of this research. This study will investigate the influence of several environmentally friendly metalworking fluids and additives types on the machining of lightweight alloys. Thus allowing the introduction of environmentally friendly alternatives with superior lubricity to current metalworking fluids. In addition to the vast environmental advantages, there would also be cost benefits due to the improvement of the machining process. It would also establish a better understanding of the interactions of environmentally friendly additives, metalworking fluids and the machining process. Finally, the results of this project will increase the competitiveness of Canadian aerospace and automotive companies by increasing the quality and throughput aspects of processes used by the manufacturers while providing a positive impact on environmental indicators.
