An Investigation of Aganoerion Polymorphum Leaf Extract as a Copper Working Fluids’ Additive

Abstract

This work presents the Aganonerion Polymorphum leaf extract as an additive for metals working fluids (MWF). The results indicated that the Aganonerion Polymorphum leaf extract additive shows high corrosion resistance and very small changes of the MWF composition as well as its properties. These benefits are attributed to the forming protective inhibiting deposits on the copper surface that control the electrochemical corrosion reactions. In addition, the study also compared the Aganonerion Polymorphum leaf extract with a commercial inhibitor, imidazolines, in investigated solution at the same experimental conditions.
