Abstract:
In this work, a novel anti-corrosion water-based lubricant is prepared. Carboxymethyl cellulose and Uncaria Gambir Extract, all in powder form, were dispersed in water. Corrosion, stability, and tribology test with pin-on-disk reciprocating tribometer were studied. The newly obtained lubricants were designated as Uncaria Gambir (UG), i.e. UG0 (0% volume Uncaria Gambir extract in Carboxymethyl cellulose, UG1 (1% volume Uncaria Gambir extract in Carboxymethyl cellulose, and UG2 (2% volume Uncaria Gambir extract in Carboxymethyl cellulose). The addition of Uncaria Gambir Extract into Carboxymethyl cellulose solution delivered good stability, low corrosion rate, and stable friction coefficient. UG1 has the best stability (no sedimentation), corrosion, and tribological performance. After a one-hour friction test, UG2 showed the best performance in terms of CoF, indicated by a 7.6% CoF reduction, compared to UG0. This finding indicates the potential of Uncaria Gambir Extract as an additive for an anti-corrosive water-based lubricant for machining application.
