| Abstract: | A novel, water‐based oleic acid (OA)/2‐acryloylamino‐2‐methyl‐1‐propanesulfonic acid (AMPS) copolymer was successfully synthesized as a water‐based lubricant additive. The OA‐AMPS copolymer was characterized by Fourier transform infrared and proton NMR spectroscopies and then used as a lubricant additive in water. The lubrication properties of water‐miscible cutting fluids with the OA‐AMPS copolymer additive were investigated using a four‐ball friction tester. The surface of the wear scars was explored using scanning electron microscopy and X‐ray photoelectron spectroscopy. The addition of the synthesized OA‐AMPS copolymer improved the friction coefficient and wear scar diameter of water. The maximum nonseizure load increased from 95 to 431 N, and the anticorrosion ability on copper was categorized as 1b. Good antiwear and friction‐reducing properties for water were observed and attributed to the absorption and tribochemical films composed of iron oxide and ferrous disulfide. © 2017 Wiley Periodicals, Inc.
