Application of CaCO3 as Anti-Friction Lubricant Additive to Improve Robustness in Sheet Metal Forming of High-Strength Aluminum
Abstract
High-strength aluminum is a good candidate for use in light-weightingapplications, but forming it is difficult due to its low formability.Elevated temperatures are therefore necessary to improve formability,but this reduces lubricant performance. The use of calcium carbonate(CaCO<sub>3</sub>) as a lubricant additive in warm- and hot-forming ofhigh-strength aluminum is evaluated by strip-drawing tests at roomtemperature, 225°C and 425°C. Further, the influence of tool surfaceroughness on the performance of the particles in reducing friction isevaluated. Lastly, the particle-additivated oil is compared to fullyformulated, commercially available warm- and hot forming oils. Theresults show that CaCO<sub>3</sub> particles are suitable for improvingtribo-systems in warm- and hot-forming of aluminum, and that they canrobustify processes where preparation and maintenance of tool surfacesis difficult as the tribo-system is less sensitive to the tool surface.The performance of the particle-additivated oil was similar to thecommercial lubricants at room temperature and 225°C, but was worse at425°C. However, due to the low cost and effort necessary to prepare theparticle-additivated oil, it is a promising alternative to existinglubricant additives.
